This is a product issue outlined in KB 1033320. If you have installed the Sage 300 CRE 20.3 Update 1 and are still having these issues, please contact support. It will be necessary to change registry to use Legacy Job setup until we are able to identify resolution of these issues that were not resolved following installation of the 20.3 Update 1

I have several clients that have the same issue - Sage support will help 

Thank you.
