@michael-s-molina thanks for the cleanup. I suspect we're removing filter box from dashboards and thus ideally we replace said filter boxes with native filters.

We can do that as a follow-up. At the moment, the focus is on removing the inconsistencies and errors.

I love this PR! I'm happy to jam with you on adding filters, spiffing up the charts, etc. if there's ever a good day to do so.
