LEAP Concrete Abutment Design Reset Concrete Strength

I am using LEAP Bridge Concrete CONNECT Edition v17.01.01.11 to design a simple span pile-cap abutment bridge.

Once I have the superstructure designed and move on to the substructure, I have to go into the material properties and change the concrete strength from 4,000psi to 4,500psi. This works and I can run my design. However, if I need to leave the analysis and come back later for any reason, the concrete strength always resets itself back to 4,000psi. This seems like it is a program bug and once I change it for each abutment, it should change the properties upstream in the main model.

I did not set this bridge up using the ABC tool as I inherited the superstructure definition from the main project engineer. Is there some way to change this permanently, or is this something that should change but is not operating properly?

Thanks!
