Windows 11 Screenprint/Snipping Tool: changing default save location and format

I noticed some odd behavior today.

With the Screenprint/Snipping tool in Windows 11 (previously set up to use the PrintScrn key), as soon as I snip or take a screenshot of the screen and before even saving, it creates a file in .png format. Should I select the disk icon it will prompt me where to save (via .jpg), but it won't delete the previous file.

Is there a tweak to stop or change this unwelcome and unexpected behavior?

Ok. Nevermind. I went into Windows Settings . My screenprint function is called Snipping Tool while Windows calls it Snip & Sketch tool in their feedback section. I noticed Auto Save has been turned on. Disabling it fixed things.
