FC number on miles+money booking

just made a miles+money booking for two UC to Dubai - we're off to Abu Dhabi for a few days relaxing

at the moment it's not showing up in my FC account, if I enter the booking ref. I can view it, but there's no option to enter FC numbers

I know there're no miles/tier points earned on m+m, but seems odd that i can't link it to my FC for reference

does anyone know if it's simply that m+m bookings can't link to an FC number, or is something amiss?

It's a known bug in VS systems that you have to enter your PNR to pull the booking up - happens to MPM and reward tickets, you will also find that on your boarding card the FC number will be replaced with 500500500.
