batch rename uses HTML

[eonekvt]

Yesterday I was trying to use batch rename in Bridge 2020 with Mac OS 10.13.6. Batch rename has always worked previously. Under new filenames, this screen shot shows what I wanted and typed in the first time. Current filename shows what it changed to. Also after I closed batch rename and opened again, the top sequence number opened to 33043 when it should have been 33033. And the lower sequence number opened to 18 instead of 19. I went back to the 2019 version and bridge had changed the file names there to the same ^SEQN^ that looks like HTML rather than the correct numerical.

When I tried to rename today I got this in Preview.

Then when I rename I get this again.
