Progress being deleted when I "Save as"
When I work on an animation project I make sure to save and then Save as and create multiple iterations of my project as I go along. I do this in the case my file corrupts and then I don't lose the entire project, as I have an older save to return to.
However, I keep getting a glitch where I will save and then save as and then quit the program. And then when I re-open the newest file all of my work since the last save has been lost. It's almost like it reverts back to a previous save rather than saving my current work. Similar behaviour to if you were to select the do not save button when you quit after doing a bunch of work on the project.
To clarify, in the below screenshot, file "Duke_MV_19" will be the exact same as file "Duke_MV_18" despite it being saved one minute after the recovery file. The recovery file has all of my work intact luckily.

This glitch has happened multiple times. Is there any fix? Am I doing something wrong?
