I solved the problem! Here’s how I did it.
When you go to the dynamic page in question, in this case, it’s the specific vehicle page > SETTINGS > PAGE INFO > The issue (it seems) was the page URL I was using from the data collection was the Vehicle Title and many of the vehicle titles were the same and that was causing a conflict. I changed this value to the Vehicle ID which is unique to each vehicle. Save. Re-sync. Re-publish and tested and it seems to be working fine now!!
Thanks @brett-haralson for the quick support replies.
