This is actually a feature of DEFAULT EQ2 suprisingly. I think its kind of a funny irony, but so many people use EQ2MAP that they seem to have just assumed it was EQ2MAP that did it
It is in fact part of the default UI from LU16 or 17 IIRC. It still works fine in default, so if its broken then unfortunately it must be an EQ2MAP issue that broke it.
