I was switching my barn names but everytime I type in mares for my mare barn or Mares/Broods it switches to geldings witch is the name of my other barn? And my other barns name changes to mare or Mares/Broods

Are you sure you have the right barn selected? I named two barns yesterday with no problem

My guess is that you're selecting the wrong barn to change the name of. It is really easy to do if you have multiple barns with the same name.

I have tried all of those
