Can't save tactics, edit default team sheets, formations, or players

If this can help to get around the problem on ps5:

• when you are in Seasons for example and you want to modify a tactic scheme. Create a new scheme from scratch and players roles as you like.
• Take note of the code generated 
• Save the scheme but as you know it does not work and all the changes are lost as usual
• At this point instead of creating a new tactics from scratch , use the option "create from code" where you have to input the code. At this point use the generated code from the step before. Your new tactic will be exactly as you created before. But be careful because you cannot modify it as the modification is bugged and does not work as you know. So what you see is what you get. The only thing you can modify are the players but nothing else. Otherwise you have to repeat the process
• Activate this tactics and at least it remains active when you go back to play. Also in game it's there.
