I'm stuck on step #2 of Einstein Analytics and Discovery Insights Specialist superbadge.  I'm getting this warning while checking the challenge:

The step "Churn Tenure' is in compact form, so the filter values need to be specifed as a minimum and maximum
The static step that feeds has the following the value:
 

"Tenure_Length": {
                "broadcastFacet": false,
                "label": "Tenure Length",
                "selectMode": "single",
                "type": "staticflex",
                "values": [
                    {
                        "display": "High Risk",
                        "value": "1 to 12 months",
                        "min": 1,
                        "max": 12
                    },
                    ...
                ]
            }

I'm using selection binding for min and max values.  The dashboard is correctly filtering:


Any ideas? 
I've tried a non-compact form step where I inject a saql fragment into the query, as well as where I inject min/max values using a range filter serialization...All these efforts end in the same challenge failure message.

Any help/suggesitions are welcome!
