Noticed it only happens with KFX, my AZW3 books work perfectly with my fonts, boldness setting works. Someone else had this bug on reddit here:

Any help would be appreciated, or am I just SOL until a new patch? Looking side-by-side the books seem to look better formatted in KFX than AZW3 so I'd like to keep this if possible.
