Unable to Alter Decking Properties in RAM Modeler

After taking a look at the lateral load distribution in RAM Frame, I would like to run my model using a semi-rigid diaphragm.  In RAM Modeler, when attempting to change my deck properties (for non-composite deck), I am getting the following error:

I don't understand why I am receiving this error.   Has anyone ran into this yet? 

I attempted to simply add a new deck type (changed the name) and clicked Add, but I still received the error above.  This has also happened to me on other project files and I have not yet found a viable workaround.

I am currently working remotely from home and am connected via Remote Desktop to my Network and Office Computer.

I'm using the following version of RAM SS.

Thank you,
