Incognito mode

I have just had to do a reset on my phone and after reinstalling Swiftkey it now changes to Incognto mode whenever I am in the app drawer. I can't read the incognito theme at all (whoever thought dark grey on a black background was a great idea should be shot), and as a result the keyboard becomes useless when trying to do an app search. How do I stop it from changing modes in the app drawer? It's not like I have to hide what's on there, it's not typing into a sensitive app, it's just the app listing for heaven's sake.
