Glitches are getting worse

Now when I drag and drop new elements into new rows. Entire rows DISAPPEAR. Not sure what to do at this moment. I’ve spent a lot of work setting up some of these pages and now think I am going to have to switch.

I shut off all possible plugins that could be interfering. All this began with I uploaded the pro plugin. Could that be the problem?
