Filter by months, months not chronologic

Hello
i use the standard woocommerce filter “filter by months”

What i see in my sidebar is this order:
– August
– January
– November
– October

…and this of course is irritating since it is alphabetical and doesnt correspondent with the normal sort of month during the year.

How do i change it so that the months are sorted chronological and not in alphabetical order?

kind regards
Axel
