Edited Rosters Won't Stay Loaded

[BarnstormerMC]

I like to edit rosters so that players will look more realistic with certain equipment changes. Like, making sure an outfielder uses an outfielder's glove instead of an infielder's one, or switching bat colors. But whenever I load my rosters the changes never seem to carry over to gameplay. I'll load my edited Rosters, then hop into a game but the changes won't appear. Then I'll go back to the editor and it won't show any changes and I'll have to reload my rosters.

Does anyone else have this issue or know how to fix it? It's really annoying.
