Right now, the equation for Current Level Branch is literally getting Level2 == Level2 which is probably not what you want.
You probably want to get Current Level from BP Save Player Progress, feed it into the bottom of the == node and the top just being “Level2”
Your issue is probably the Save Game object, it isn’t saving the Current Level string. Right now, you’re just telling it to set the variable when you get the Save Game Object and reference from there which is probably not the intended function.
How are you saving the Current Level string?
