It's an issue with the way the opportunity is programmed. It's programmed for the locations in Sunset Valley and Riverview, which are different in Bridgeport. For example, there's Doo Peas Towers in the original towns, but it's named something else in Bridgeport and it's attached to another business. The game can't process it correctly. It's a bug that will have to be fixed by Electronic Arts. Until then, you'll just have to cancel those opportunities.
