If I understand you correctly, you see the same problem when running
fping from the command line. So the problem is not in Smokeping at all.

Maybe something is rate-limiting your ICMP packets? This could be a
host-level firewall (netfilter/iptables) on the local host or a device
between you and the targets.

Other than that, no good ideas. Sorry :)
