User Interface Is Disappearing In Editor

It wont let me view my previously added user interface but i can see it when i play the game. Why does this happen?

[Please leave the link to the game when asking about a problem or for help]

are you on the right layer?

yes i was, i found out there was no real reason i just had to click where it was supposed to be and it appeared i have no idea why this is

You can only view the layer you are in, not sure if that helps.
