Subdomains got mixed up

Hello,
I have multiple subdomains in my WordPress multi-site environment, but after I added site (countries) all of them got mixed up.

Is there an option for Windows Server / Plesk Onyx / WordPress 5.3.2-de_DE

Permalinks postnameor me to re-sort them, so that subdomain a.domain.com is on top again, and the last one to be z.domain.com?
Thanks!
