CC-BY-SA doesn't allow you to "combine the two into one dataset"
unless that one dataset is CC-BY-SA.

I'm not sure why non-clarity makes it a moot point.  If you don't
clearly have a license, then you shouldn't use the work at all.

But as long as you release the combined dataset under CC-BY-SA, there
shouldn't be a problem.
