Smart Function Kit for Handling IO setup

I get an error when I try to save the "Inputs and Outputs" Settings. 

I have just upgraded the SFKH app from 2.0.1  to 2.1.1. This update broke the System Function allocations and I am trying to fix them. 

I can't see the "Status" Blue Dots changing when I press the attached buttons. 

I assume the CtrlX Plus drive has version 1.12 OS. See attached systemreport for details.  Do I need to upgrade this to work with SFKH 2.1.1? 

Or do I need to take the SFKH back to defaults and start again?

What else can I try?

Also, in this version of the App there does not seem to be any way to allocate an input to Clear Error or Error Reset. I can't see anything like this on the list of System Functions. How do I clear errors from a physical input?
