Listbox sort date MMMM YYYY

[Michaels]

Hi, 

I have a field Date formating like  this : January 2019, February 2019, ...

I have a listbox with field and I would like to sort by decreasing date, I try with  date#(Date, 'MMMM YYYY')

Data is correctly sort when there is no selection but when I select one date the other are group by month : 

December 2020
December 2019

November 2020

November 2019

Any ideas ? 

Thanks

Are you using this as your sort expression? date#(Date, 'MMMM YYYY'), may be try using this instead

Only({1} Date#(Date, 'MMMM YYYY'))
