How can it send them if you disable link local addressing? Yes, this. There's no benefit to disabling link-local addressing, and doing so can definitely break other IPv6 features. I've never seen an explicitly-configured link-local address before, but I'd be really surprised if it worked as a replacement for the automatically-generated link-local address.
