Quoted from PinballCoug:I had this very same problem, increasing coil strength did not work, opened a ticket and was sent a video to gently realign the geometry. Easy fix and haven't had an issue since. Below is the link CGC sent, see if it works for you.

Thank you for this! Been having the same issue on my SE and it is the only thing preventing the table from being perfect
