I saw something like this recently in a little different context. In the
output of a babel block I saw the empty table get inserted around the
results. It only happened in one file, and I didn't notice if there was a
user-error.  I can't reproduce it at the moment, and didn't spend any time
tracking it down. If I see it again I will see if I can track anything
down.

I am using Org mode version 9.2.1 (9.2.1-23-g126a37-elpaplus @
/Users/jkitchin/vc/jkitchin-github/scimax/elpa/org-plus-contrib-20190218/)
