If you check the Tcl Console, is a message (CRITICAL_WARNING or similar) written out regarding this constraint? It seems like PlanAhead may have had an incorrect check on this value on expecting it to be 0-31.
It would be best to check this in a 13.x version of planAhead. If you don't have access to this you could create a webcase and work with support to see if this as been fixed.
To work around this issue you can set this propery in the UCF (see the cosntraitns guide):
Make sure the UCF constraints ends up in the <projectname>.runs/<run>/<run>.ucf. If planAhead is dropping the UCF cosntraint as well, then add this to a separate UCF, do NOT include it in the PlanAhead project, and feed to NGDBuild by adding a "-uc" switch under "More Options" in the PlanAhead strategy.
