Approach not approved

When I enter the flight plan and I want to fill in the approach, it displays an error that it is not approved to approach via GPS. This was not displayed by the Hondajet aircraft. It is already displayed. The only aircraft that does not have a problem with this is the Cirrus Vision Jet. Can anyone answer me? Thank you.

As i understand and think;
you are selecting an ILS/LOC or else approach, are you?

As i understand it, only RNAV (and co.) are approaches via GPS. ILS and LOC are „conventional“ approaches and they don’t use GPS. Tha‘s the reason why you get this „error“. It‘s not a really error, it‘s just a information.
