Altitude constraints on LEGS-page

Hello, first of all I want to say thank you to PMDG for this wonderful addon ;). Just a little thing that I've just seen on a flight. The BELOW-operator on the LEGS-page in the FMC doesn't seem to have an effect. The FMC's descent planning ignores the constraint: If I only type 120 instead of 120B it works: It would be nice if you could consider this for the next update. Thanks :).
