Can't Display Albums and tracks

Hi Everyone.
I have a simple problem that has me stumped. I have just upgraded to V2.81 and on opening the app and using the "change directory" button, I select the folder to load OK and the App reads the contents of the folder but fails to display the the contents in the MP3Tag windows for editing. I am reading the files on a NAS QNAP TS-412.

MP3tag has always worked without fault in the past, however I haven't used it for about 6 months.

Any suggestions please?

Changes to my system since last using MP3tag include moving to Windows Defender and the usual Windows 10 and QNAP updates.

Thanks John

Have a look if you still have an old filter-expression active. (F3)

Thanks Mate. That did the job, I can see the track details now.
