Realm backups not showing

Recently had a moderator/operator of the server use the /kill @e command without telling me. Lots of progress was lost. I though we could just load a backup but none are showing. This is very frustrating, as I remember backups working flawlessly in 1.14, so I'm unsure if there's no backups (unlikely as a backup is created every 30 minutes and last I checked the world said that it had been online for 280 in game days) or if they're not showing. I really want to get back to my world, so please tell me what's wrong or if there's a fix.
