I would check the coding and the waypoint...unless it is part of a coded procedure that you already have, there may be issues...
The waypoint is part of a system, it can be high/low, have a min altitude, and/or be a part of an approach/departure.
I have seen this attempted use before, when the waypoints denoted a procedure that had TF and RF legs snaking a path along a mountain range...
the system would vector to the nearest waypoint on the route, but because the route doubled back around a mountain ridge, the system vectored the aircraft through the ridge, as this was the shortest distance between waypoints
(ref the southern approach to CYLW, Kehlowna)
Picking a waypoint and using the vector can be an issue...
