The dark alley.
Do not touch “Fix issues” ever, it will ruin everything!
I can list hundred more scary quotes that various iOS developers will tell you. And for years this was actually close to the truth, as Xcode’s integrated attempts to ease the management of the profiles were less than stellar.
This is extremely complicated and convoluted part of the iOS developer life. Apple recognizes this and Xcode and iTunes Connect / Developer Portal teams have worked for years to make this work seamlessly.
So next time when you are fed up with all the nonsense and just want to burn it all – go and do just that. Seriously, make a clean start.
