Budget sheets not showing actual spend anymore

A few days ago all the budget tabs seem to have been disconnected from the transactions. There’s no actual spend showing on Monthly or Yearly Budget tabs. And the Insights tab has transaction counts for top 10 transaction inflows, but nothing for the other 3 top 10 categories.
Any ideas for a fix?

It sounds like the maybe the formulas linking to the Categories sheet were damaged, @carla.bobka.

Honestly, since issue is recent, probably the easiest thing is to use the File / Version History / See Version History and just revert back a few days to when the spreadsheet was working.
