Hi guys I had a bit of problem with my computer

So I had to reinstall everything but I've notice that the

Setting for my speed , heading ,altitude have changed

Pictures below thanks !!

What exactly is wrong with them?

For some reason the farmat has been change for example look at the heading

In the picture above it's saying HDG 16 instead of HDG 016 , the altimeter is saying ft 1000 instead of ft 10000
