Hello Rob,

I have tried this in both 24.5.1 (the version that ships with
Fedora 23) and 25.1-rc1, which I downloaded and compiled
specifically for this test.  In neither case did your bug show up.
When I positioned the cursor over the "a" and hit C-k C-k, the
letter and then the blank line disappeared as expected.  The rest
of the characters remained as expected as well.

I am left to suspect that there is something amiss with your
setup.  I'm afraid I have no idea what that could be.

Sorry I couldn't be of more help.
