Subform not updating when changing selection in lookup field

Subform not updating when changing selection in lookup field

Hi
I can select my lookup field selection:'quoted service' from one app, which is looking at all records in another app, that match this client and are accepted.

The problem is if there is more than 1 accepted quoted service.

I can see it in the lookup field selection:'quoted service', but no matter which selection i choose , it is only retrieving the data from one of the accepted quotes to populate my subform data. Any ideas?
