Are the IRB67xx series robots not compatible with IRBT6004 in RS 2024

I need to put a IRB6740 on a 20-meter track with dual carriages.  I ran into issues when trying to create my virtual controller from layout, I through everything but the kitchen sink at it, and the last straw was testing with a fresh instance of robot studio and putting the 6740 on the simplest 6004 track possible and I still ran into the "This combination is not supported" error.  

Any help or ideas on troubleshooting would be appreciated.
