Can I ask, what is the use case? The reason it’s happening is that the incrementing is done in CSS and it assumes that you’re starting at 1.
This is a solution you can add as a CSS snippet, but it isn’t a very elegant solution because I don’t think it can be done generically
ol[start="2"] { counter-reset: counter 1;}
ol[start="3"] { counter-reset: counter 2;}
ol[start="4"] { counter-reset: counter 3;}
ol[start="5"] { counter-reset: counter 4;}
ol[start="6"] { counter-reset: counter 5;}
ol[start="7"] { counter-reset: counter 6;}
Alternatively you could create a snippet to remove the ol styling altogether.
