Options in filter added in external career site no displaying in order

Summary:

Hi Everyone,
We've enabled field "Experience" as filter in external career site
from HCM Experience Design Studio action:- Recruiting - Define Career Site Search Filters
however it's not showing option under filter in order.
As you can see while filling job req options in field "Experience" are in ascending order

and we expected the same when we enabled the filter but options in field "Experience" as filter in external career site are not in order

Can you please let me know if this is feasible or not, if yes what steps needs to be taken here.
Thank you.
