I used to have a Seasure furler too but it wouldn’t furl with the tension on. Tired of releasing the tension every time I wanted to use it, I switched to a Harken High Load furler and swivel, that solved the issue. As Dave already wrote, a furler that doesn’t furl well may twist the wire and perhaps cause the damage you describe. For starters, check the top swivel. It should run smooth under full load, if not replace it by a High Load type.
BTW, On my current boat I have a Bartels reefing system which is even better then a Harken High Load furling system.
