When you connect the device, calibre should update the collections on the device. To do that, it requires the options to be set in the driver, and the metadata management option on the "Sending books to devices" page of the preferences to the set to the automatic option. The latter being wrong is a common reason for the collection management not to happen. You should check the configuration. There have been resetting of configurations with calibre updates. It shouldn't happen, but, it seems to. And, one it does happen, it is to late to work out why.

Another reason is changing between the KoboTouch and KoboTouchExtended drivers. While the options are the same, they are not shared. You need to configure them separately. And if you change between the drivers, you need to manually copy the options if you want them to be the same (though that is a good idea for my Kobo Utilities plugin).

The other thing is that the collection management is only done for books on the device that calibre has matched to books in the current library. The collection management will only be done if there book in the library has a green tick against it indicating it is on the device.
