Placing Reinforcement in Deck give "Command not Defined for this application"

When trying to get to place reinforcement in a concrete deck using ProConcrete within OBM. I get "Command not Defined for this application."  I am using OBD Version 10.10.20.34 and have placed the "Slab with Constraints - 2 Lanes" loaded in into the model.  Please to not suggest "upgrade to the latest version of OBD as an answer!  Sometimes that is just not possible.  Thank you!
