New version not working on Filename to TAG

Hi guys

I am trying to convert filename to TAG on a couple of albums and even though the preview works perfect, its not overwriting the data in the fields

I have tried several times to no avail

Any suggestions?

(I have deleted the Artist field and it still does not work)

Your mask creates a user-defined field ARTISTS (with an S at the end). The standard name is ARTIST or ALBUMARTIST - with no S at the end.
Check your files for a field with the name ARTISTS
