When trying to download realm backup it says I am out of storage even though I have plenty left

When trying to download a backup of my realm on my Nintendo Switch I get a popup that says, “You are almost out of storage space! Minecraft has restricted access to this feature until you clear up additional storage space.” I have 89.6 GB of storage free. 

 

Steps to recreate:

1. Have a realm and some backups on Switch
2. Try to download any of the backups
