Trailer TPMS screen display issues

[Burns363R]

So i got my trailer TPMS all setup. Selected 4 tires, did the learn procedure, got the 4 honks, and completed the learn. When the trailer tire pressures are displayed, it shows 6 tires on the trailer, with 2 not being used. They middle pair just show a straight line for pressure? Is this normal? I would think the display would only show the 4 that I programed.

Do you have a picture to show? I didn’t even think you could get 6 tires to be monitored with the kit.
