Tire pressure not reading after new tires were installed.

I just had mud tires installed on my 2017 Tacoma TRD Off Road. Ever since I got the truck back, the tire pressure screen on the dash will not show me the tire pressure. It just shows "----" for each tire. However, the low tire pressure indicator is not on. I did not have this issue before they changed the tires. I took it back to the place that put the tires on and they tried to reprogram the sensors. Nothing. I still have the factory wheels and I only have 850 miles on the truck so I doubt they would change anything with the sensors. Any idea what's wrong?
