Kindle PW3 - Caecila Condensed with KFX broken

Hello,

is it just my Kindle PW3 -(up to date firmware, 5.8.9.2) or is Caecila Condensed generally broken on KFX format books?

The letters seemed to be zoomed/distorted horizontally (like zooming a 4:3 movie to fill a 16:9 monitor), and Caecilia Condensed is not Condensed anymore but takes up a lot no *more* space than Caecilia.

I have attached a couple of screenshot:
1 KFX with Caecilia Condensed (Character Size 2)
2 For comparison the same page (KFX) in Amazon Ember
3 How it should look like, Caecila Condensed on a AZW3 book.

tia, cu Andreas
