I still can't see the proper event structure but it sounds like it is changing the character level in the same tick so it changes character level to 1, which is true for the event below then changes it to 2. You can put it all in one event with sub events/else so it checks the level and only runs one of the actions.
So if level = 1 do this else if level = 2 do this, not separate events down the sheet.
