get-pnpfolderstorage metric retrieves negative value

[IanRamsdenBCC]

I'm at a bit of a loss as to why this is happening, when I run get-pnpfolderstorage metric on a library I get this back

LastModified TotalFileCount TotalFileStreamSize TotalSize

---

17/02/2025 15:17:53 0 0 -47874475131

however if I run measure-pnplist I get this back

ItemCount : 3
ItemVersionCount : 0
FolderCount : 4
TotalFileSize : 42730
BrokenPermissionCount : 0

The Measure-pnplist seems to be retrieving a decent file approximation

interestingly when I run storage Metrics on the site the libray looks like this

Any idea why this maybe happening?
