2 Lot Tracked Parts always default to Main Warehouse for Order Release

We have 8000 parts in the system but only 2 are lot tracked. Anytime someone puts an order on for either of these parts in any of the 13 warehouses we have, the order Release defaults back to our main warehouse each time. All parts are setup in their own Site with their own Warehouse as the primary, just like all other parts we have. Does anyone know of why a Lot Tracked part would only default to the main warehouse each time?

Stumbled on the answer here. Our sister company hosts our Epicor with theirs so they do work on our server at times. Someone in Accounting asked them to make a New Product Group for both of these parts, so when they made the group they left the Sales Site field set to the Main warehouse so it pulled any orders to that site.
