Lookup filter bug in iOS app?

I am testing the Coda app for iOS and it works fine for most scenarios but there seems to be a bug in the lookup filter. The filter options show twice with different formatting. Or maybe I have some settings wrong?

I just noticed that the same happens in the computer browser (Chrome). If this is only happening to me I obviously have an incorrect setting somewhere.
These are the lookup settings:
