It’s at the heel so more likely the other end of the loaf got stuck as it slid in, and this end never made it to the wires. Then the whole loaf got pushed into a bag as usual, the front end having been dislodged by the vibration of the slicing process.

One time I dropped a cookie on the floor and by the time I picked it up it was the size of a trash can lid

OP might be able to run a tape measure through it to separate the bread from the bread material.

We don’t. Such a tool does not exist. Any attempt to cut already sliced bread into thinner slices will only ever result in a pile of crumbs and tears.
