When my Inspire 1 is on the ground the VPS displays a red "0.3"  instead of 0.  Anyone else having this issue?

No terribly unusual ,  mine does that sometimes as well .

There is nothing wrong with the vision positioning / ultrasonic altitude system reading from your Inspire 1.

The system reads the distance between sensors module and the ground, which distance is 0.3 foot when the aircraft is in landing mode sitting on ground. Red colour is a warning to the pilot when such distance is small, reminding the pilot about the likelihood of aircraft hitting the ground.

I would concur with Henry,
