The pcap capture shows the IPv4 ping is encapsulated as an IPv6 packet and sent on the wire.
However the remote end returns an ICMPv6 indicating an unrecognized next header type; I suspect the IPv6 destination option could be the problem.
Are you able to run the same test on a lede-17.01.4 build ? It would be interesting to see if the IPv6 destination option is included as well in the IPv6 packet containing the IPv4 ping
