Conflicting Interactions Bug


Recently finished a site, but seem to be having two interactions conflict with each other, which cause the overflow on my Navigation to turn into a scroll.

As such the Cart does not display properly.

On the interactions (whilst scrolling) I have one to scale the nav and change its background colour / text as it passes by a certain percentage.

I then have another interaction (page scrolled) to hide or show the nav if scrolled up or down.
This seems to be the interaction that is causing the issue.

I’ve probably missed something obvious. But currently for the life of me I cannot see it.
Any ideas would be greatly appreciated.
