Hi @kalyanchakravarthych,we had same issue in one of the environment and was able to identify one scenario is when we save the CF and if you don't close the window then every 10 mins autosave event is triggering and after sometime it is sending empty key value pairs to save.To stop the autosave even...

I had same issue, so I resolved it by adding like this(<a href="link" _rte_href="same link"></a>) to <a> tag.
