Try disabling these first to see if the behavior goes away. After disabling, be sure to restart Cinnamon before continuing. Right-click an empty portion of the panel, select Troubleshooting, then 'Restart Cinnamon'. Alternately, you can open the run dialog - Alt-F2, type 'r' or 'restart', and enter.
