Merge is not working for my current STLs

I am trying to make a multipass first layer mulicolor print.. which I have done before, but my models won't merge probably in line with one another... anyone know if this is a bug or why this may be happening?

    First go into the cura  preferences (not project settings).  Go to menu item "Preferences" (or Alt+R).  Then "configure cura".  Make sure "ensure models are kept apart" is unchecked.  Pay attention to "Automatically drop models to the build plate".  You may want this on or off. Not sure. Alternatively you can click on each part and the move tool and set Z to zero.

     

    I haven't done this in years but I just played with cura a bit and I didn't use the "merge" feature.  Instead I added both models, right clicked on each one and assigned a different extruder, then I right clicked on each and did "center".  That seemed to work well.

     

    It looks to me like your "rocket" model should possibly be scaled down.  You can click on it and use the scale tool and then recenter if necessary.

     

    I don't think there is any need to "merge".
