well, i got the same american samoa replacement with one core zara, and tested before posting., it did solve it.
after checking other voices, same thing with one core marc, , sapi5 zira and david. British voices don't have the problem in the first place, so I would assume only american voices are affected.

switching caps did not work here, nor could I think of a same sounding replacement for as, so i haven't got any simpler solution coming to mind
