I edited the plug-in to protect certain shelves, namely the date added, date read, and a bunch of others.

I decided that I needed to upload some titles to GR. My settings have a sync that only syncs the specified GR columns, however I noticed that the sync changed my date added to Jan 01, 0101 when the date added shouldn't be effected at all. That particular date shows up when I import blank info into that column---like when I download the GR CSV and update the "date added' when there is no date...Fortunately I have access to the original dates.

I went back to confirm that that shelf was protected, it was. I proceeded to "unprotect" all the shelves so I could edit that date added, but now they won't allow me access regardless of what the plug-in specifies.

I cannot access ANY of the shelves that have at one time been protected.

I purged the library specific data, the JSON, and eventually removed the plug-in all together, but I still can't access those shelves. I restarted Calibre each time, I confirmed that I removed the plug-in, but still when I go to edit the metadata I can't access a lot of columns.

So....why did the date added column change when it was protected, and why can't I now access it and a bunch of other shelves now that the plug in has been removed.

At this moment I cannot do anything with my library...just sitting here with nothing to do about it until I get access to those shelves....

Also note, this happened today AFTER I reinstated the protect columns option. That option also would not update to my current calibre view settings, the old ones that I have long since changed were the only ones to show up. I entered the data for the new view that I was using. This was the view that was effected, but all the other views still won't show up those columns.

Update: I don't know how the JSON came back, but I found it in the plug-in folder, I just deleted and restarted Calibre and now its fine. Sorry to bug...

second update: I spoke too soon. I assumed that Calibre would be fine after deleting the JSON, but I still can't access those shelves...
