In Studio 2021, Although "FIG." is set as an abbreviation in the segmentation rules (it's actually one of the presettings), all my English source segments are split after "FIG.". So why does this not work?

I tried. Same results. All segments are split after "FIG.". Very annoying!
This is such basic functionality there must be a more fundamental problem here. Please can you verify or comment on:

I actually solved the issue yesterday night. I had to create a new template from scratch with that TM.
I had been using the same template with that TM and was under the impression that any changes (such as editing the abbreviation list) to that TM are effective when using the template.
