Tabs get stuck on a chapter after I switch tabs

Hello all, I have a peculiar issue, but it is quite annoying. I have a tab for seminary, a tab for home, a tab for sunday school, and a tab for priesthood. However, I noticed that every time we read with our family and I switch back to my home tab, I get sent back to Deuteronomy 1, even though we read that ages ago. Anyone know what the issue could be?

I'm not sure what would cause the problem, but have you tried creating a new screen for home study, and deleting the old one?
