Guys,
First, thank you very much for your patience and hints in the last couple of days. Much appreciated …
We worked hard over the weekend to identify and solve the issue. I have built revision 2, which is available now via the Navigraph Hub. Please update your current cycle 2501 with this revision for MSFS 2020.
We have done a lot of tests now, and it looks good to us that this issue is solved now. Any feedback is welcome 
Cheers,
Richard
