Some loot messages oddities

[Hyperiel]

The bards reborn student of song - USSEP patch. I have a message saying I don't have it. The bards reborn student of song page has a patch that covers bards with USSEP and AI Overhaul in one. I have it, and get that message.

Zim's Improved Dremora with USSEP. I get the message that I don't have it, but there is another USSEP patch for this mod that lets dremora spawn at higher level. thats what I use but still get warned about missing USSEP patch.

Last one. Books of Skyrim. Got a message about the update mod Books of Skyrim Redux. I installed it, and the warning persists.
