Remove A Perk

So my dumb ass while prestiging my survivors in cloud editor i failed to realise i had added the un-added bill perk "last standing" was wondering if theres a way to get rid of this?

How are you using cloud extract and save editor without a bypass since it's been patched, are you using a paid private bypass? Just remove the perk via save editor.

Thing is i did try to delete it in sav editor, clicked the "del" key, didnt delete- was wondering if i prestiged the character back down to pres 2 it would be removed?
