Your monitor is upside down. Turn it over and that should fix the problem.

In all seriousness though, I've never heard of such a problem before.

You'll have to forward that to the creator of those maps, they are the people that have to fix it.

Can you post an example mission and a screen shot?

This is the recycler on the map brick in the wall.
There are other units nearby, but they are completely submerged.

Please comment on each map this occurs on. I suspect it's probably a group of Battle Grounds maps, which are far and away the oldest on the workshop and are therefore full of all kinds of strangeness.

If a map or mod ever replaces .vdf files, I imagine something strange like this could occur. It might be a good idea to deactivate all mods, and check if this issue exists in the campaign. 99.9% of us don't have this problem, so it must be something specific to your installation.
