Problem with attachment versions


I seem to have found an issue with attachment versions. I have updated a new version of a pdf, and now have V1 and V2. When i open the attachment, V2, all is fine and I do have the most up to date version. Problem is when I open the attachment version history, then V1 shows the latest version and V2 shows the older version. You can see in the snip below that V2 on the right was uploaded at 20:35, but on the left it shows V2 20:32 and V1 20:35!

Am I doing something wrong or is this a glitch in the system?
