We're using the Pivot Table with dynamic data, with possiblity of label being the same. Hence we opted to use the data's id which is a GUID for the pivot field name instead.
This is causing issues for the value field settings form as it is using the field name as a class name selector - this occurs when the GUID starts with a number.
We're hoping this could be fixed on the module's end as while we could remedy this in some way like prefixing the field name with text, it will break existing data. This is also exposes our GUIDs as it seems to be getting used as a class name for some of the components.
Thank you.
