FluentForms Email Notification Merge Fields

Hi there, I'm trying to merge in fields from a post into an email notification that goes out from a form submission. I'm using ACF and am trying to merge in a custom date field. Currently I'm getting a version of the current date in a weird format (this is what I'm seeing: _Z20250630.06UTC30pm.UTC000UTC630_08UTC30pm34Sunday06_UTC000UTC630_08pm30UTC.06/08/2025) in my notification instead of the date in my custom field. I tried modifying the format per the documentation but haven't had any luck. I've got a ticket in with support about this already but was wondering if anyone else has been able to use this functionality successfully and have the date display correctly.
