What happened

A total was set that the column's type cannot support - a sum of dates, an average of text. The total is refused rather than computed, because a number that is arithmetically valid and semantically meaningless is worse than no number at all. The message lists the reductions the type does support.

The fix

Use one of the reductions listed in the message, or change the column's type if the type is what is wrong.
