We had the same issue with MX960. There is no evidence in any IPFIX template send by the Juniper that it is sampled IPFIX. Although it is sampled forcing the sampling rate did the trick here too. Thanks for pointing this out. I already tried it with setting the sampling rate in nfsen.conf but missed the option "-" to force it. Without "force" it does not work.
