Yes, I have had this. It's some kind of odd combination of both the battery and the cart.
I've had it happen with both blanks and prefilled, particularly red blanks and spearmint prefilled. For some reason, it only happens on my black manuals, but those same carts
thread just fine on my silver manual or diamond. It's not consistent either, it only happens once in a while. Almost all carts will thread onto the black manuals just fine.
Sorry I can't be of any help, but you're not alone!
