Cannot import "recycle binned" file from audio pool

Yesterday i accidentally deleted an audio part from my project, saved it and closed it. Today I noticed it and wanted to reimport it from the audio pool by drag and drop (as I usually do). Somehow it did not work. It showed me this symbol :no_entry_sign:, also I could not restore it with any of the menu options.
Then I tried the same with a file which was not in the recycle bin and that worked fine. In the end I had to use the “Import audio file” option and manually search the file in the project audio folder to reimport it.
Whats going on here? Cant remember I had issues with the pool on version 9.5?

Am I really the only one having this problem?
