Sohpos 9.4.1 wont let me add new custom scans, delete old ones, or modify them.

I am running Sophos v9.4.1. I set up some custom scans a while ago. I went to change one of them and add a new one. The program will show the new custom scans until I quit the program. Once I reopen Sophos any changes I made to the custom scans has disappeared. I have also tried deleting the custom scan and it will reappear when Sohpos restarts.
