What am I supposed to be seeing?

As you say, this VM only has one snapshot. However, it has three VDIs registered, none of which is the base image, so I assume that you've been mixing linked cloning with snapshots.

It may be necessary to for you call it quits with this VM. It the VM still works then what I would do is do a full clone of it: full (not linked) clone, current state only (i.e. do not preserve snapshot structure), don't reset MAC addresses. This will give you a standalone clone VM, and temporarily require up to 80GB of disk space. After testing you would eliminate all of the older snapshot ridden relatives, recovering your disk space.

Ok, that sounds good. I will start the clone now, and post here how it goes. Thanks for your help!

Ok, I cloned the VM and have now finally reduced my storage usage. Thanks for the help, looks like I am all set!

Glad you recovered your space... Marking this as [Resolved].
