Ahhh got it. The setting was Airspace_AOR_Airports=OM
However, now I seem to have another issue. The tags are now showing the first three letters of the destination airport in the FCOPX item. So for example "OMD" instead of "DB". I'm not able to figure out how to fix this.

I have the following settings configured in the Settings file.
Label_COP_MaxChars=3
Label_FCOP_MaxChars=3
Label_ADES_MaxChars=2
So the way I want to set it up is for a FCOPX fix such as "MEMTU" the label should show the first three letters, so for example "MEM" and for the destination FCOPX the last two letters so for example "DB".
Would it be possible to have an option to facilitate this?
