Save FX Channel

Hello Board,
have a question, may someone can help me ...

I use the FX2 section for the Master,
because of that I click on the "M"

but everytime I reopen "Rekordbox" it stands on "2"
that means, every freakin´time I open it
I have to open the FX-Section, change it from "2" to "M"
and close the FX Section again

anything I can do, to save this setting ?

thanks in advance :-)
