Game incorrectly listed as having in-app purchases on Google Play

My current project is in alpha on the Play Store and it’s listed as containing in-app purchases which it does not.
I am working on getting admob ads in but surely those wouldn’t be listed as in-app purchases?

Any ideas?

I assume this has something to do with permissions - admob ads seem to require “com.android.vending.BILLING” as an extra permission.
Can anyone shed some light?
