DVB S2X MultiStream dual Tuner

  • Good morning,
    I have a query. I ordered and received a should be DVB S2X MultiStream dual Tuner for my DM900UHD. BUT this Tuner which I received does NOT have
    on it's printed board an ''S2X-MS'' and it MOD date is 2016/4 (Si21662 Dual REV B2) whilst on the package box the date is MOD 2017/6 si21662 B4.

    Now when I tried it the MultiStream Bouquets they remained 'greyed out' and also when I did a manual scan on one Multistream Frequency, nothing was
    scanned in. I came to the conclusion that I was given another type of Tuner but not a MultiStream one.
    Can anyone please confirm my conclusion to be certain that this is the wrong Tuner.
