I have 3 tires that display psi on touch screen but 1 tire displays dashes.tire light is not on. Anybody seen that concern

Dashes can means lost communication with the sensor in the tire. The sensors battery may be dead or has other problems. Are all 4 tires original and still have the sensor installed?

Also try resetting the system. The owners manual should have something like this.
