hidden noteheads show up in print

So far I have been hiding noteheads by setting the opacity to 0%. In Engrave mode they nicely disappeared.
In Print mode (and in the pdf…) they are back in full glory.

Is this there a setting I can adjust, is it a bug or is this not The Best Method To Hide Noteheads?

Thanks!

Make sure you print in colour.

I love you.

I love you too.

I love both of you.
And be it just for that post!

Hey, we ALL love each other here! We are the living embodiment of the Beatles’ song on that subject.

In fact we all love even the occasional nay-sayer who posts here, and you can’t get much more loving than that!
