Disappearing Completed Tasks in My Day View

🤔:magnifying_glass_tilted_right:  Lately noticing that when I complete something on :bright_button: My Day list, the completed item disappears. 😱

I save my lists with all the completed items every day for my records (as well as to have back-up of everything I do.)  I've tried with all versions: web/online, desktop app and mobile app but the completed disappear from My Day list into the Completed list, which is not sorted by date.

Is there a way to fix it so that the completed items remain in the "My Day" list? 🙏🥺
