Existing Music Collections Missing in Windows Desktop Add To for Tracks

Server Version#: Version 1.41.0.8994
Player Version#: Windows Version 1.102.0.230-7301ebfb and Web Version 4.136.1

Selecting ‘Add to Collection’ on tracks turns up an empty list of collections.
Albums work fine. Not sure if this is related to smart collection creation?

Personal Media for music on this server has priority for agents on this server.

Only manually created collections will be shown, because you cannot add tracks to any sort of smart playlist or smart collection.
Those are solely based on the filter conditions which were used to create them. If you wish to extend smart lists, you need to “Edit Filters” on them.

These are manually created collections.

The same issue occurs for albums in search results.
