G1000 MFD button inoperable

[WrightFlyer]

Hi,

It appears one of the buttons on the G1000 MFD is inoperable. It is the fourth button from the right. I am not able to select WX when I navigate to the WPT page. Also, in the flightplan page, I cannot select CUM. This does work in the standard Laminar G1000, but not for the SR22T. Is this a known issue?

Thank you!
