I have a bedrock realm that I play on with my friends, and sometimes when I renew it, rather than giving me 30 more days to play, it creates an all new realm with a random seed, and does not renew the old realm. I now have like 4 realms due to this bug and I can only renew the latest one.

This happened to me as well. It gave me the popup warning about expiring the first time. In my realm settings it shows "renews every 0 days" instead of every 30 days. And when I clicked to renew I got a new realm and had to pay another subscription fee to Microsoft and my original realm still did not show as renewing (even though microsoft will definitely continue to bill that subscriptin. So then I went to the original realm settings and it showed as having "no subscriptions" so I clicked on 10 player subscription from inside the realm's settings and again it create a new Realms subscription. This is really an issue. I closed the two new realms and cancelled the subscriptions at Microsoft but the damage was already done. I had paid for both of them and my realm still doesn't show as renewing automatically.
