Is your eccentric lever on your Fathom a little loose?
This is my son's. I don't fish it. A while back I replaced the Eccentric with the new improved version.
Then the lever came loose from its shaft and I just put in a new one. It works well enough but it seems that There should be a thicker washer or bushing.
That screw is notorious for coming loose. You need to cock the spool back up bit before putting it in free spool, especially if there's pressure on the line. Takes some getting used to, I've had to tighten mine up a couple times. Love the reel though
