Supidest accidental mistake

I was testing the solution for the Add Two Numbers problem(2 lists with digits where you make 2 reversed numnbers from those digits and add them up) on VsCode by myself and as a test i chose the most genius lists - [3,2,2] and [2,7,3]. My code didn't work and didn't reverse the numbers, but I couldn't know it, because 322+273 equals 223+372. So I literally accidentally chose 2 numbers that add up to the same number reversed or not, and misled myself. Btw I'm new to coding and leetcode. Literally started it few days ago and this is my 3d problem, and got interested in it after web dev course in uni where they taught the most basic JS.
