'CSS Scroll Snap causing duplicate div temporarily on android

OK, so on all devices this site is behaving as it should. However on nearly all android devices, including Browserstack I'm having an issue when you scroll past "Treatment Options" the content gets quite 'shonky'. Is anyone aware of a bug or something I'm doing completely stupid? dev site: http://eqp.isitmeanttodothat.io

TIA
