table header is appearing as a footer for some pages

We use a template for storing meeting notes. Beginning 10 Dec. the table within our meeting notes displays the header at the bottom of the table in read mode. In edit mode, the table header appears at the top as expected.

Probably not relevant, but looking at pages saved before 10 Dec, all tables appear as expected.

Attaching a screenshot, the bottom section "Item, Who, Notes" is expected at the top of the table.
