hi, i am in the process setting up an agent, i uploaded a pdf of all the inventory, when i made the call it was able to find and share some of the inventory, when i asked if there was more expensive ones, it did find those, and then asked which car did i want to test drive it, i said sure, the second option, then found a totally different car and started talking about that one. when i showed the demo to the client, he was impressed but also concerned that it was giving wrong information based on the pdf provided in its own conversation. is there a way to manage this so it doesnt happen?
