Deleted my other world but still can't create a new timeline.

I had my free timeline slots used already, but I wanted to create a new one so I deleted an entire world I wasn't using, along with it's timeline. But it still isn't letting me create a new one, saying my slots are full. I currently have no timelines.

Steps to Reproduce

1- have free account
2- create a world and fill timeline slots creating timelines
3- create new world and delete the first one
4- try to create new timeline in the new world and fail :(
