Has anyone else had this problem?
It is not clear what problems you are referring to. Your tabs and contents are not intuitive to me.
I am having a problem with Tabs, that is not present when built with v11.02 on coworkers laptops, but I am seeing it in v11.1.1.
I reproduce my Tabs issue with v11.04 as well. When I downgraded to v11.02, my problem with tabs went away.
I have one tab defined for Mark only. That tab does not show up unless the app opens to Mark initially, but if opened to Mark initially then the tab shows up for all books. The contents for the undefined tabs just shows the normal bible text same as the primary text tab.
If the app opens up initially to Matthew, then neither Matthew nor Mark have the added tab.
