Keeping manual sort order after selection

[#1]

I have a manual sort order on a list box using the below expression:

match([Month],'Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec')

However, when I make a selection my choice jumps to the last selection option - how can i keep the same order even when a selection is made? Please note that I have already unclicked the State option.

Many thanks.

match(only({1} [Month]),'Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec')
