Sorry, for the late answer : I was gone for few days. So, thanks to you both !

I guess that you are talking about the
View>Color notes by...>Track command in the MIDI editor. Indeed, when gluing the edited item, it resets itself to 'Velocity', instead of staying on 'Tracks'.
I have no explanation for this and it doesn't seem to be theme related, as it behaves the same way with other themes, including the default one. Beide this, I see no options that could control this behavior, so I'm unable to help, sorry...
