This screenshot represents 3 saves, in one folder, using one name, the same name every time.

I have used the name 1876 AP Test all 3 times I saved the equipment file and I have a 1876 AP Test.eqp..eqp. file, a 1876 AP Test.eqp.砀⥹. file and a 1876 AP Test.eqp file, and the changes I just made in that last save of 1/3/2018 will not load.
I saved them, went and tested 1 round of combat and reloaded the scenario and it said 'wrong eqp. file' and is showing me the state of the equipment file from 1/1.
Why won't it overwrite and only leave me with 1 file? Why are the names so crazy? How do I keep from having to deal with this issue?
