That depends: what did you do with those 5 certificates?
It seems you're haphazardly creating a lot of certificates recently: https://crt.sh/?q=mail.tvnl.eu&deduplicate=Y May I remind you that testing should be done against the staging environment?
Also, I don't fully understand what's going on here anyway. You seem to have perfectly fine certificates which include the hostnames mail.tvnl.eu and tvnl.eu for a while now. And now you're running into rate limits for certificates specifically for just mail.tvnl.eu? What's the purpose of that new certificate? Why not just use the old one?
Also, since March 2021 for some reason the www subdomain was dropped. Just noticing that, maybe that was on purpose, maybe not.
