Thanks Umberto,
ORBX gave me that answer
"The most important is that there is no Vector AEC correction for LSGG,
so whether or not the control panel recognises it is not really relevant.
Secondly, it remains perfectly possible to manually disable AEC for a single airport.
It is only the auto configuration that does not recognise the xml entries.
There is only one file for LSGG in the entire ORBX folder.
ORBX\FTX_VECTOR\FTX_VECTOR_APT\scenery\ABP_LSGG.bgl.
If you disable that, rename it to ABP_LSGG.bgl.off, you will have none.
If your problem goes away, all good.
If it does not, you will need to return to the FSDT forum and share with them the advice I have just given you."
Unfortunately this did not help.
