How do I remove my bookmarks from the "Awesome Bar" predictive search on Android mobile?

I have successfully prevented my bookmarks from showing up in the "Awesome Bar" address bar predictive search on desktop by going into the Security and Privacy panel and turning off that option, but even though my Firefox Sync is set to sync options, my Firefox browser on android mobile keeps showing my bookmarks in the predictive search. How do I make it so that my mobile doesn't show me my bookmarks in suggestions in the address bar at all?
