You are correct. Changed for the next update.
My original design had 14mm bolts if I recall correctly here. Hardware was changed so that the assortment of lengths would be less. This is out of my control.
BTW, I do design work on the side for Folgertech. However, final design and hardware is out of my hands. I am aware of the issue.
Thank you very much for taking the time to submit feedback, it is greatly appreciated.
