I am still seeking help for this issue as well. Anything you p[lace in trips defense gameplan copies itself and overwrites wildcat defense gameplan during the save playbook process. Anything you p[lace in Nickel defense gameplan copies itself and overwrites Overload defense gameplan AND the bunch defense gameplan during the save playbook process.
So while editing trips, you are also editing wildcat, edits become visible on save.
While editing Nickel, you are also editing Overload and Bunch, visible on save.
While editing wildcat, overload, and bunch, you aren't doing ANYTHING (your edits will vanish), visible upon save.
This was madden 16 in my case, a year back, and I spent about 4 hours on the phone with tech support, the resolution being they would submit a bug report. This dramatic response (sarcasm) followed me doing everything that can be done to a PS4 short of having sex with it, including actually replacing the PlayStation, with no effect.
TLDR: Dfensive Gameplan is completely broken, and EA wont acknowledge it let alone fix it, even going so far as to allow the bug to live on in the next madden.
