What is causing Vapi to modify my "first message"? We formatted to make the agent pronounce numbers correctly. A few days ago it worked fine. Now it's transforming my exact text strings...? First Message: "Hi, I’m looking for 10 Yards of Nine Thousand P.S.I.. Actual First message.... { "role": "bot", "time": 1736327036095, "source": "", "endTime": 1736327040315, "message": "Hi. I'm looking for 10 yards of **9000 PSI**", "duration": 3980.000244140625, "secondsFromStart": 1.36 } This is causing my agent to say "9 0 0 0 psy" / "nine zero zero zero psy" in the conversation. As opposed to "Nine thousand P.S.I." Super annoying. Anyone dealing with overwrites?
