Header rows setting changes after saving and re-opening word file

Question

I want the 1st two rows of my table to repeat as header on every page. 

What I did:

I highlighted the 2 rows > right-click, table properties > row > ticked "repeat as header row at the top of each page". It looks fine and appears as I wanted it to.

What happened:

Once done, I saved the document. However, upon re-opening the file, the 2nd row of my header is no longer repeated (only the 1st row is repeated). I have also noticed that now the "Allow row to break across pages" tick box is a solid square, it was definitely unchecked before I saved and re-opened.

It might be beneficial to mention that my header design is such that it was initially a single row, then some cells in that row is split into 2 rows. My problem is that the 2nd row although appeared fine once formatted, it isn't repeated anymore once I save the file and reopen it.

If you send me a copy of the document, referencing this thread in the covering email message, I will investigate the issue.
