how can i do to send exactly 10 000 DRIP to masternode?

i tried several times but the transaction shows 0.00000000DRIP and the address is n/a...

i tried to send it with "send as-zero fee transaction if possible" but not works. And always appears me that i send more DRIP than i set

i would apreciate an answear because otherwise i can't set my masternode...

thanks
