Statements tab has gone sideways - help!

I opened Tiller a few days ago and noticed my statements tab is messed up. It looks like coding is off.
The dropdowns in cells are wrong and I have no idea where to begin (bottom image dropdown should be offering dates). Can someone look at it and give me thoughts about what might be wrong? It was “normal” and working great last week when I reconciled and I haven’t changed anything that I’m aware of.

First thought might be do you have anything available under “Edit” → “Undo” on the sheet? Wondering if an edit/change might have caused this?
