Heyo Captain,
It looks like you are using modificiations on your client. These can mess with key game files and make things inaccurate.
I would recommend removing your mods and seeing if the issue persists.

That is fair, but also look at the cap locations on these Screenshots... the islands are in their prior location on the mini-map before they were shifted North-East. Last time I checked there wasn't a island in the middle of C.
In an unmodded client:

As taken from your replay on a clean client:
It is the map mod you're using that shows the size on the top left of the mini map, please remove your mods and you should not have this issue.
Fem,
