Question / Help Duel screens?

[Program]

So, I was messing around with OBS and I somehow got 2 preview screens by accident, and I don't know how to fix it https://gyazo.com/7bb81a2389999b142bd4e23000015080

This is the OBS Studio "Studio Mode".

To exit Studio mode, look to the lower right corner and hit "Studio Mode" ONE time. This will revert you back to Classic Mode.
