Appian Designer Folder size difference

Question

Hey Everyone, Not a technical issue just a question about the folder sizes in Appian. When I'm looking at folder I can see it has a size of 48.2 GB. 
 But when I open it to see what is inside of it there are only a few items, where the size doesn't reach anywhere close to the stated 48.2 GB.

We have the same issue in at least 2 of our large knowledge centers. As far as I can tell, the issue mainly stems from documents that were originally uploaded under a particular root folder / KC, but were then moved elsewhere. Apparently Appian doesn't actually calculate the sizes correctly in these cases - and in my case even, running a "getDocumentsFromFolder()" on the root folder in question turns up results that actually aren't in that root folder. I have had a few different support cases regarding this issue in the past few years but not much luck yet getting any sort of automated resolution.
