Bug? Create DDL Option - Deselecting FK still produces SQL with FK

I’ve tried many times without luck. I deselect FK in the script creation and it still creates FK at the bottom of the script. I’ve to manually go and remove that as I don’t want FK in the creation script. I create FULL DB script for deployment on test servers so I want script w/o FK to start with. Later I want ONLY FK script that I enable after data load.

Please help as because of this possible glitch I cannot automate this task.
