Context Menu for packing slip not pulling correct record

I set up a dashboard which displays the columns RcvHead.VendorNum, RcvHead.PurPoint, and RcvHead.PackSlip. When I go to the right-click Context Menu from Packing Slip, it won’t pull the correct packing slip into Receipt Tracker. It will be the same packing slip number, but it might be from a different vendor. Shouldn’t the Context Menu link validate all of the key fields, including the vendor number?
