Both the text and the background is white.

I've recently fixed this in the code (e86a689) but haven't had the time to fully test my updates and make a deployment for this! Thanks for the report!

Just a heads-up that this currently happens on the Statistics page also.
I've not looked into the code, I'm not (yet) familiar with React or programming for Android, sorry!
