Date Format Changing when Published to SharePoint

I have created a multi page report with a date slicer formatted to drive other metrics through the report. Published from desktop to Power BI service with no issues, however when I then publish to SharePoint online the date format in the slicer changes, which is then affecting other elements in the report causing data to display incorrectly. 

PBIX Date Format: Day Month Year (30 September 2022)

SharePoint Date Format: Day, Month Day Year (Friday, September 30, 2022)

Very confusing! Any ideas?
