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, https://renesasrulz.com/synergy/f/synergy---forum/11895/error-filex---usbx-host-updating-to-ssp-1-5-3-and-e2-studio-v7-2-0.

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

Kind regards,

Rene
