Teleporting animation

So, I made a animation of a stick figure climbing a ladder. And I converted it to a symbol so I didn't have to remake the frames each time. I had the symbol go a total of 5 times, it only messed up on the last 3 symbols, I DID classic tween the last 2 symbols but I don't understand why the first symbol would be impacted. Is there a way to fix this?

Also please ignore the people in the back, even though I'm in class my teacher is just not helping me so I'm asking here.
