Hi,
It seems like you are still running the old beta version of the In-Game Panel. You can see it says “Navigraph Charts BETA” in the titlebar.
Please see END OF BETA: Thank you for all the feedback! where you are asked to manually remove the beta panel from your Community folder, and then install the Charts 8 In-Game Panel from the Navdata Center app.
Charts 8 In-Game Panel works fine in SU12:
Kind regards,
Stephen
