Incorrect supplier site on contract purchase agreement when raising purchase requisition

Summary:

we are using contract purchase agreements and when raising a requisition, selecting the agreement.

one of our users selected the wrong supplier site when creating the agreement. they were able to process a change to the agreement to select the correct supplier site.

However, when we try to raise a requisition, the old incorrect supplier site is still showing and not the updated one.

we are new to using purchase agreements. I have checked the configuration pages under configure procurement business function but I cannot see anything related to this.

I am thinking maybe there is an update scheduled job that needs to run, can you help?
