Thank you for all your feedback on my question, I really appreciate!
I went back to the company and pushed and they agreed to redo it, however their solution has been to do a much bigger bit of lead than they had originally. I’ve attached a picture, but I think they just replaced the slates on one row and then put the lead on top.
Will this be ok? Are there any negatives? Do we need to push them to redo again?!
