new text appears on my screen flying Yak 7b career

[PeaceO]

A new text appears on my screen when I fly my Yak 7b career. On the left side of my screen is a green "max 000" and on the right, a red "max 000". Turning the pilots view changes the value "000" up to 350. This text is not present when I fly my Bf 109 e7 career. Could you be so kind as to help me get rid of this text?

Deleted that instance. Started a new one. Text gone.
