Cubase remote control and plugin focus problem

Hey there nice people…
I spend a lot of time yesterday in google to find the answer to my problem, so if it was ever mention before, means i did not search well enough.
I am learning to use midi controlers to control plugins via remote control function. Setup seems to be easy process, but i arrive to the point that i can not move forward. I am using Console 1 device in midi mode trying to work with Fabfilter proq 3. I am able to control just one instance of plugin and only if is in the same insert slot i was setting up. I have perfect template. Of course i was trying the focus option where are 3 possible options. This change totally nothing. I presume that focus plugin means that i move the mouse coursor on the plugin and i click on it…? However, i was trying many different ways and still i am not able to control more than one instance of fabfilter plugin. Any suggestions very welcome
