OK, after a bit of investigation. Is the intent of the "for AB 3.2" ruleset to be always enabled? If so, you should simply delete the "legality" expression of that ruleset ("ro_bFormat"), and this problem will go away. The legality expression is currently:
Which strikes me as odd - if you want it to always be active, you can just specify no expression at all. Is there a reason you can't do this?
AB appears to be not selecting the ruleset properly when the file is loaded, which I'm investigating now. But I can't think of a reason you can't just delete the tag expression and have everything work.
Hope this helps!
