The first issue I see is the OUTPUT TO LIGHTS box isn't checked.
Second, you have skipped DMX addresses between 3.180 and 4-181 on the E682 setup.
Your Nutcracker setup is configured up to address 510 on universe 3, and starts on address 1 of universe 4. You need to correct that. Those 2 areas need to match exactly.
I too use 100 light strings in 50 light increments. I configure the Nutcracker model 100 nodes per string with 2 strands per string. I leave the E682 fold unchecked.
Start with those fixes and post back the results.
