Reforged Campaign keep autosaving each checkpoint

Hello there!

I’m playing the Reforged Campaign and I’ve an annoying issue: each checkpoint of the mission the game archive an autosave, so at the end of the match I’ve my original save and other 5/6 with the name of the chapter.

An example: if I play 3 chapters in a row then I want to save and exit, my save’s dropped at the bottom of the folder submerged by autosaves.
I’ve not flagged the replay’s autosave, never wanted it neither searched. May I get help? Can’t find anything to fix the issue on settings.
Thanks in advance
