Glo Font issue

I have 2 font problems I am hoping you guys can help me with.

Problem #1:

When I go to change the font of a book I'm reading, the list of fonts repeats itself, so each font set is listed twice. I have not sideloaded any fonts so these are all the fonts that came on the Glo. This has only been since I upgraded to 2.5.1. The list of fonts looks like this:

Amasis
Avenir Next
Caecilia
Georgia
Gill Sans
Kobo Nickel
Malabar
Gothic
Amasis
Avenir Next
Caecilia
Georgia
Gill Sans
Kobo Nickel
Malabar
Gothic
Ryumin
OpenDyslexic

How do I get rid of the extra sets of fonts?

Problem #2:

In the "Advanced" area for each font (that has that capability) how do I reset them to the default? When I hit "Reset", it only puts them back to the setting I had before I changed it, not to a default for the font. I could swear I remembered it resetting each font to a default when I hit "reset" before I upgraded to the new firmware, but maybe I'm wrong. Either way, is there some way to get the fonts back to their default settings? Because on some of them I like the default better but I can't remember where the sliders were.

Thanks in advance!
