Sling firing by itself?

[Lickashot]

Put some new rubbers on all my slings today (don't even ask about getting the AC/DC cannon off ) the left sling on my IMVE fires once by itself at the start of a new ball. Doesn't have any issues at all after that, any ideas?

Maybe the leaf switches needs adjusting?

Tried that but it just happens once at the start of a new ball.

Seems fine now, just needed a little bit more bending.
