Ok, digging deeper into the code… It seems the date is still being pulled from the legacy anniversary or birthday fields. And that is set be the list_type. The upcoming templates will need to be updated to pull the date from the modern date data.
It just so happen that I am working on the block equivalent for the upcoming list for the new WP 5.0 editor. The plan is to support lists for any of the registered date types. So, I will have to update the template code.
I do apologize for the inconvenience, but, the next update should automagically resolve this for you. Hopefully I can get this out later this week.
