I have this code:

      {
        "active": true,
        "chain_settings": {
          "chain_links": [
            {
              "action_name": "Single Field Edit",
              "action_settings": {
                "col_name": "#kobocoll",
                "template": "program:\n\tg = field('#genres');\n\tk = field('#kobocoll');\n\tif list_contains(g, ',', '^Fanfiction$', '1', '') then\n\t\tk = list_union(k, 'Fanfiction', ',')\n\tfi;\n\tif list_contains(g, ',', '^Cozy Mystery$', '1', '') then\n\t\tk = list_union(k, 'Cozy Mysteries', ',')\n\tfi;\n\tif list_contains(g, ',', '^Horses$', '1', '') then\n\t\tk = list_union(k, 'Horses', ',')\n\tfi;\n\tif list_contains(g, ',', '^(Fantasy|Science Fiction)$', '1', '') then\n\t\tk = list_union(k, 'Fantasy & Sci-Fi', ',')\n\tfi;\n\tk",
                "value_type": "template"
              },
              "comment": "Update #kobocoll column"
            },
            {
              "action_name": "Calibre Actions",
              "action_settings": {
                "disable_busy_cursor": false,
                "selection": [
                  {
                    "display": "Send to device",
                    "path": [
                      "Send To Device"
                    ]
                  }
                ]
              },
              "comment": "Send to device if device is connected",
              "condition_settings": {
                "cmp_type": "=",
                "datatype": "text",
                "template": "program: connected_device_name('main')",
                "value": "Kobo Aura HD"
              }
            },
            {
              "action_name": "Calibre Actions",
              "action_settings": {
                "disable_busy_cursor": false,
                "selection": [
                  {
                    "display": "Add to list: Send to Device",
                    "path": [
                      "Reading List",
                      "Add to list",
                      "Add to list: Send to Device"
                    ],
                    "paths_text": "Add to list|Add to list: Send to Device"
                  }
                ]
              },
              "comment": "Add to \"Send to Device\" list if device is not connected",
              "condition_settings": {
                "cmp_type": "=",
                "datatype": "text",
                "template": "program: connected_device_name('main')",
                "value": ""
              }
            },
            {
              "action_name": "Single Field Edit",
              "action_settings": {
                "col_name": "#onkobo",
                "template": "program:\n\tif and(\tcheck_yes_no('#onkobo', '', '', 1),) then \t'False' \n\telse 'True'\n\tfi",
                "value_type": "template"
              },
              "comment": "Set #onkobo column"
            }
          ],
          "refresh_gui": true
        },
        "image": "sync.png",
        "menuText": "Send to Device",
        "subMenu": ""
      },

However i noticed a slight glitch with it. When I eject my Kobo, sometimes the conditional doesn't update (the template value in the evaluator confirms this) and it tries to do the wrong actions (and predictably fail) the next time I run the chain. When this happens my two greyed-out chains are also available.

Any idea why?
