This also happens on Macs. ID 14.0.2, Mac OS 10.14.3. I've reverted to ID 2018 until this is fixed.

Is there a reason it has to be a header, yet not behave as a header by repeating at the head of frames/pages/etc.? If it's only to be on the first page, there's no reason I know to have InDesign treat it as a header. It sounds like it is a body row, just with special formatting to distinguish it from the actual table body.
Am I missing something?
