GUI Disappearing in Blueprint Editor

When I create a blueprint in the editor it opens up showing the GUI and all the option, etc.
When I close it and re-open it the GUI and options disappear, I’m sure it is an easy fix as I am very new to UE4.

Here is a video showing what I mean.

This definitely looks like a bug. Have you searched around to see if others are having this issue?

Yes, I’ve looked around haven’t found anyone with a the same or similar issue.

Have also tried re-installing the engine, still getting the same result.

Fixed it by going to the Window option and showing the Class Defaults, then it gave me an option to open the full editor!
