Double date picker is displaying

I think that this relates to the changes in 📌 Remove dependency on jquery_ui_datepicker Needs work . where the input type is being changed from text to date.

If custom code adds the datepicker, this would cause the duplication.

Does it happen without any custom code applying to the form inputs?

Since there hasn't been a follow up going to close out. If still an issue please try the 7.0.x branch
