Padauk font Bloom to SAB/RAB transition

Hello, I am wondering if anyone has ideas for dealing with Padauk not showing up correctly in vowel combinations with ေ when creating a book in Bloom and making an app with it using Bloom Player through RAB/SAB. The text, typed by someone else who probably has an older version of Padauk font, looks fine in Bloom and in the Bloom Player, but then in the subsequent app created through SAB, any occurrence of ေ creates a dotted circle and the consonant gets pushed to the other side of the vowel.

It seems to be fixed if I re-type the material myself in Bloom, which is a work-around, but not a true fix. Just wondering if anyone else has had this issue and if it is known where the problem may lie.
