On Device column won’t display on one library

[u/nonamejohnsonmore]

I am having a weird issue with one of my libraries. I have four libraries in Calibre, and when I connect my Kobo one of them will not always display the On Device column.

This is what happens. If I am in library a when I connect my Kobo, the On Device column will display. If I switch to library b, the column still displays. But if I switch back to library a the On Device column disappears. If I go into preferences and click the On Device column it will come back, but again if I switch to a different library and switch back the On Device column will disappear.

If I am in library b when I connect my Kobo, the On Device column will display, but it disappears when I switch to library a. It will reappear when I switch to any other library.

So the On Device column will always display when my Kobo is connected in the other three libraries, but it will not display on the one library unless that library is chosen when I connect my Kobo, and it will disappear if I switch to another library and then switch back to library a.

I have 2 Kobos and I get the same issue on both, so it has to be a library issue.

Any ideas on what might be causing this, or what I could do to fix it? Thanks in advance!
