i got the Amsterdam to work with the gates at the right places
but then coming off 09 i was going under the airport in the taxiway
i was reading up on it as you see in the attachment so i replace it and now i got the ground that has hill dips in it it was fine apart from the plane going underground but now the airport looks worst

please could someone tell me how to fix this issue the ams v2 been a big issue and not been able to use it and ended up walking away from it as it was useable
