Synergy configurator displays this error: express logic source and pre-build library should not be combined in the stack configurator

I'm trying to add filex on usb host using the Synergy configurator for a S5D9 mcu and i'm getting an error with which I have no idea what to do.

Im on SSP 1.6.0 and E2 studio 7.3.0 and adding to stack: X-Ware -> Filex -> FileX on usb storage.

Looks like this.

I have no idea what to about this error message. I found a post on this forum but that solution did not help for me, or i'm doing something wrong,

Has somebody got an idea what to do or at least get some more debug information?

Kind regards,
