Only got two attunement slots

As it says on the tin, for some unexplainable reason my dnd character sheet is stuck with only 2 attunment slots, i dont know if there is a new rule about being limited to only 2 slots?
I really dont want to remake the entire sheet 
But so far I have tried with no results:
- Remove all of the cleric levels
- Remove all of the artificer levels
- Remove all of levels
- Change class
- Copy sheet
- Removing the custom background

Any help would be really appreciated. 

Here is the sheet
