Minecraft Xbox one edition world isn’t appearing in the “sync old world” tab on the newer...

Hi everyone,

I’m trying to transfer an old world of mine to the newer version of minecraft but in the “sync old world” tab, it doesn’t appear. The latest known save for the world in question is 7/20/19 but when in the “sync old world” tab it only shows a saves from 6/8/19
and older. Im assuming it’s a glitch in the cloud or something but any tips or suggestions would be helpful. Thanks!!

:)
