Altimter Range Colur Bug in all Airbus Aircrafts

Hello Sir,

I am in the Beta Channel of the Aerofly FS 4 Steam. Recently, after a couple of flights I noticed that in the alitimeter bar within the PFD of all Airbus Aircrafts the Range Background Colour is in Red, though even my altitutde is 35000ft or 1000ft. That, Red Range Bar Colur should come at only negative altitudes but I am getting that colour in all altitudes. Attaching, an image below for your reference. I though it might be a software bug from my end so I re-installed the Sim, even tried with the Non-Beta Version but still it is the same. Can you have a look to it.

Hi Jan,

I already set a route a from Kathmadu to Peru from the Navigation Panel. When, I cleared that route the altimter bug went away. Thanks.

But, though in the Navigation Menu I set that route, I was not flying that route. I was flying randomly around the world, then why will the altimter show that Negative Altitude Bar, though my QNH is set to ISA Standard 1013hPa, even when I was flying over Europe landing in Zurich, that Red Bar was showing. Is this an issue? As it should not happen.
