Default Pawn overrides my character

So i created a FP character in 4.2 that works flawlessly
After attempting to recreate it in 4.3. it wont work because when i hit play, default blueprints are generated such as;

DefaultPawn17
HUD17
PlayerController17
gamemode17
etc…

My pawn and gamemode is being overriden by the defaultpawn.
and none of my created gamemode,pawn, or hud show up on runtime (which they used to)
instead the default ones do.
so How do i turn off the defaults?

1.go to your project settings and make sure it was set correctly.
2, in your level, press the world settings button and check in detail tab to make sure you don’t have any manual override.

Problem solved.
I set the gamemode override to my created game mode.
Thank you.
