Content selection checkboxes do not show content in updated version

Observed behavior

Using the IMPORT MORE function in Kolibri shows two videos in the testing folder:

Expected behavior

There should be three videos in that folder, two alrady on device and one new

see on studio.

The db file served by Studio is v2 and it contains the new video.

Kolibri also seems to have read the correct DB file during UPDATE CHANNEL wizard, because the UI shows there are 7 content items in the channel and 6 already on device: so problem seems to be just related to the selection component.

User-facing consequences

Users will not be able to import new content added to their channel.

Errors and logs

No errors in the logs, just standard import logging.

Oh, actually read through your scenario - yeah, nothing here would fix that, because that wouldn’t be counted as an upgrade, and we have no other way of knowing that any change has taken place.

Fixed in #6533
