Save device/saving in general

Hey i was just working on my map in uefn and dealing with score and save devices but i just noticed that it does not work anymore i have a player refrence device and ive set add 1 score on each elim however when killing players the score stays at 0 and does not increment at all. i went to another project a new one and the save and score system worked perfectly there. tried to delete the save device and reset all my progress and just have so it counts when i kill someone. also looked at settings to see what was different and made it not work but no luck there. Is my map/project completly destroyed or what can i do?

Same problem. Save Device does not save score
