Game says I'm out of space when I have 80 gigabytes left on my console

Basically, when I either attempt to access the Marketplace or play a world of any kind, I get an error saying I'm almost out of storage space, which makes absolutely no sense because the My Games and Apps section of the Xbox dashboard says I have plus or minus 80 gigabytes left. I am not curerntly enrolled in any Minecraft beta programs; however, I have enrolled my Xbox for beta updates (although I am on a release version at the time of this writing). Using the very glitchy magic of Edge, I have imported external resource packs into my game, as well as a few worlds, so this might be the issue, but I'm not sure.
