Date type format set in Table, not respected in Visual (format MMMM yyyy, is plotting as DD/MM/YYYY)

Hello. Any help would be appreciated. :)

I'm setting a column to reflect dates as:

    Data Type: Date

    Format: March 2001 (MMMM yyyy)

Within the Table is shows the Data as above.

My issue is the visual is just a veneer, as if I use the drop down filter I can still see the value as DD/MM/YY.

So when I try to plot this as a visual I'm getting plot points for DD/MM/YY and not the MMMM yyyy.

any suggestions please?

Thanks
