Players & Teams feedback Megathread

Whenever I alter a team sheet, save it, finish playing, then reload the game, everything has reverted back to how it originally was. Also some teams are completely locked so you can't move anyone around, even after a formation change. This was a huge bug I had in 25 & I'm shocked it's carried over onto 26, what's going on here? It's such a fundamental part of the game, to create team sheets, tactics etc but nothing saves :(
