Map RF/FF issue

We have the following issue with Spectacle Blinds

Rule:

(OPM_MATCH_PROPERTY_MAP_FACING = C;D|E;F|RAISED_FACE;FLAT_FACE|FLAT_FACE;RAISED_FACE|RAISED_FACE;RAISED_FACE|FLAT_FACE;FLAT_FACE)

This works fine with mating flanges RF/FF.

When placing a Spectacle Blind between a RF / FF flange pair, it does not work.
