Default [Q] Store keeps disappearing


I have just installed this ROM ( ) and I want to thank you for this work.

Although, I have some problems:
- the Google Store is not showing up in the menu. I tried installing it separately, but after rebooting, it will still disappear.
- when I get into landscape mode, I can't see what I am writing (because the background is black and the text color is black too)

How can I solve this problems?

Many thanks.
