Hi, I am not an expert at all on Paphs.
All I have learnt in the 3 yrs I have had paphs, is, that they take Longer than other orchids to grow & bloom.. I only have 5/6 and out of those I have only had flowers on a couple (at least they last

)...all I can say is Patience! the growths have to mature before you see flowers & that takes AGES... also yes I agree that I have found that in my conditions they need to be wetter than my phals for example. ..
and one that has re flowered recently has been about 1.5m away from a SW window, getting afternon sunshine this winter & decided to bud..
I Don't know of it's because of the sunshine or because it was mature & ready?
Hopefully an 'expert' will chime in here..
good luck ! ...patience is the 'key'.....
