I disconnected my external monitor. I also connect the mouse directly to my surface pro. It was previously connected through a USB hub port. My moue now triggers the edit. Before I figured this out, I contacted the customer service and they showed me how they could easily move things around and edit but my mouse was half unresponsive, I didn't realize that the issue was the mouse-PC connection. My previous setup did not have any issue with other purposes. It was problematic only with squarespace. Hope this helps with others who are having the same issue.
