Open Level Not Working!

All im trying to do is simply open a level but most of the time when i click the button it just dosent load. I say “most of the time” because about 3 times now it worked for maybe 5 - 10 minutes then went back to not wanting to open the level i have a picture of my blueprint as well as a gif image of me trying to click the button. Again “most of the time” i just click the button and it resets the level. Is there a bug with open level? am i doing it wrong? please help thanks in advance.
