SDP 7.5 Beta is very buggy

I hoped I am not the first one to test out SDP 7.5 Beta. I was evaluating SDP 7.0 and decided to try out 7.5 Beta since it has so many new features. I installed 7.5 and accidentally remove 7.0. Anyway, it doesn't matter since I am trying out 7.5. Once I logged in to SDP, I changed my Administrator password for easy login. I tried to save it but the Save button had no response. I cancelled it and it work.

Next, I tried out the new Drag and Drop feature in the Request Customizer. I dragged out 1 box and it turned out to have a gap in the form. By right, drag and drop feature should allow auto-placement of the fields but this one does not. Instead, you have to manually place all the fields at the desired area.
