I have defined a couple of Stages (Stage 1 and Stage 2) for my flow and embedded a component to show the stages in my 2 flow screens. When I start out on the first screen Stage 1 is correctly highlighted. However when I click Next to move to screen 2 I get this error that I cannot make sense of:

The delimiter of Stage 1 stage is missing.

I have not been able find any information about this cryptic error so I am hoping others have encountered it and know what it means or that SF can shed some light on what this means.
