Got 2.0x instead of fixed surge in Philly

I live in South Jersey. On Saturday Nights I usually set the destination filter to west philly hoping to get a pax to pay my toll for the late surges. Tonight I got a ride into south South Philly. Before I dropped off the pax, with the DF still on, I got a request for Xfinity Live and it said 2.0x. I was sure it was a mistake, but took it anyway. I was wrong, it actually gave me the 2.0x. I'm hoping someone else doesn't tell me it was a $15 surge there at that time
