Abutment issue when using lxGenFromSource

Hi,

I am doing a gen from source using the following skill command:
lxGenFromSource(cv_schematic ?layLibName schLib ?layCellName schCell ?layViewName "layout" ?initDoStacking nil)

then moving instances (using the dbMoveFig command) in the newly created layout via skill script. However, I am seeing that the abutment of devices is not working properly (ie. contacts don't get dropped and parameters relating to left/right dummy poly are not updated).
Is there a way to abutment works properly via skill script instead of having to go in and manually fix all of the devices which should be abutted?

Thanks,
Elizabeth
