Unless you've missed out the olive, it's not 8mm.

(but you don't need an olive if you have a reducer??)

I'm guessing you have a reducer for 10mm microbore. It should be a very
snug fit before tightening up the compression fitting. If it's
definitely an 8mm reducer, then you aren't tightening it up enough)
