Can you elaborate a little bit, eventually with screenshots demonstrating what you mean?
I just tried joining your sever, while being in "gg_kx_zuckerzeit", and had no issues at all.
Only issue is if I disable download with the content filter of the game, e.g.:
^ With this marked setting, I got "Missing Map", but with any of the other settings in there, it worked fine.
Different sizes can be because the downloads has been interrupted, if you have interrupted a download of the map previously, the map may not be complete, and therefore you cannot join because the map files (client vs server) are two different ones.
But that thing shouldn't say "Missing Map", but instead refer to that the "map file differs from the server's".
