MRP job created Process MRP NOT CHECKED

I have apart that is on sales order and it keeps creating MRP jobs. I have unchecked the Process MRP on the part but it keeps recreating the jobs. I did have one that had a demand link and we deleted the demand link. When i try to clear unfirm jobs it keeps telling me there is a demand link.

Seems like something is not resetting. Is there a conversion?

Any help will be great.

Thanks Kim
