LW Address populating in VW as Dimmer

It sounds like the mapping between Lightwright and Vectorworks is set incorrectly. In Lightwright, be sure that Lightwright's Address field doesn't map to the Vectorworks Dimmer field.

And in Lightwright 6, you don't use the LW dimmer field for addresses, that's what the LW Address columns are for - unless you're in Legacy mode, in which case there are no address features and it works the same as in LW5 - which is definitely much more limited.
