With CE V15.3, a new message in the error window will appear : "Inconsistency detected in one or more DFBs"

To correct the issue :
1- Do an export of the "Derived FB Type"
2- Import back the "Derived FB Type"
3- A pop up opens called "Import Trouble Report" , select "Replace All":

4. Build and save the application.
