Can't Expand Default Lot Size

[Maui Dave]

I'm designing a home on a lot. The default Dreamplan lot isn't large enough to put the home on the lot at scale. Need to make the lot bigger. Software won't let me. 

Any help would be appreciated. If this can't be done, I can't use the software and will need to get a refund. 

Thanks in advance.
