Why do the Advance Design options change dramatically without editing?

Hi Team.

I would like to ask why the advance design options always change the current design of my form without editing it ?

and the following image 1.2 

I realy dont know if it is only happening to me or others experience the same.

Please Help me with this issue.

Thank you.
