Hi,
before I create a Support Ticket, I just wanted to check if there might be an underlying reason for a behavior in the DSD Design generation:
1. create a default DSD with e.g. 5 factors and generate the design. the Color Map will show all main effects and 2-factor interactions
2. Create a default DSD with 5 factors but change one factor name e.g. X1->test. generate the design. The color map will now only show main effects.
I checked the custom designer, there the map does reflect the change as expected and does not remove interactions.
I think this is a missed implementation (rather than a bug) but should be changed. However, there is a chance there is a good reason for it 
Thanks for feedback
Martin
