Oh no. This gives me a clear:

Invalid capture filter: "not ether dest ff:ff:ff:ff:ff:ff"!

Like I said before: when I choose it from the list, it works. It is just and easy: "not broadcast" :-)  So this is not the problem.
The "problem" is, that the display filter doesn't work. E.g. like this:

!(eth.dst == ff:ff:ff:ff:ff:ff)

when I am in Monitor mode. This doesn't filter the ff:ff:ff:ff:ff:ff packets at all. Neither does this: !(eth==ff:ff:ff:ff:ff:ff).
And I don't know either how to filter all those packets away with another SSID. I just want my packets with SSID=mywifi and want to filter SSID=otherwifi completely out.

Kind Regards,
