Fusion 360 Source File Duplicate?

[Rwings39]

If I'm not mistaken, it looks like the "Vertical Locking Spacers Part 2.fd3" and "Vertical Locking Spacers Part 3.fd3" files are identical? Even the file sizes matched when I downloaded them. I'm not sure if this is a duplicate from saving version histories in Fusion and there should only be two sets, or if there is a set of Locking Spacers that's missing.
