Trying out 2.38 and I noticed that when I now do a Quick Action of Replace and select _FILENAME for the field that it reports back that both 4 of 4 Tags Formatted and 4 of 4 Files Renamed. Shouldn't it be 0 of 4 tags formatted.
I look at the tag information and nothing actually seems to change in them.
If I do Replace _ALL then it reports both Files and Tag formatted and it does change them both. If I do replace _TAG then it reports only Tags formatted, like it should.
So, it seems that Replace _FILENAME reports back that it formatted the tags when it actually did not. Maybe a bug?
