Media Publisher don't accept my Shot naming

Hello
I am naming my XML sequence shots in this fashion:

SHOT_P<segment###>0_
which renders as a name:
SHOT_P0010_S039 as it shows on my clip

Inside Media Publisher, I followed by letter the instructions by Grant Kay, and there is a warning that keeps saying I am using ‘.’ as a filename starter as the screen shots suggest.
Somehow the shot naming using tokens creates a name that Media publisher sees as a name that starts with ‘.’
Anyone crossed that issue before?
Best


Yes, although I seldom use Publish, so I don’t remember the circumstance. I think I did a full restart (power down and up again) and it got better.
