Hi Andy sorry for late reply.
Confirmed that it works fine in P3Dv4 but I managed to try one in my version of P3D v3 (which is similar to a new version of FSX) and yes I see the problem is with Thomas Ruth versions of the MD11. As this stage I don't know why but there will be a fix. Hopefully I will have time to try a few things and if so I will upload revised versions because it is probably a few tweaks here and there.
Meanwhile if you want a MD11 (one of my favourite aircraft!) try some by SMS
