Can of tomatoes removed issue

So Barry goes back in time and puts back the can of tomatoes.

But that causes problems so he goes back in time again to remove the can of tomatoes again.

But wouldn’t his mom look at the cart at checkout and say what happened to the can of tomatoes and either goes back and gets it since it is required or someone in the store gets it for her.

Maybe that is what creates the new timeline where Batman is Clooney now
