You said "When you click on the REMs it deletes the wheels (normal until then) but when you reload the morph again with the INJ and put the wheel on 1 the morph is doubled, you have to put it at 0.5 for it to be correct."

Did you add those five lines to the REM files as well? Using the REM should completely remove the parameter dial that you injected (one REM each for the number of injections you added). Then it wouldn't double up if you inject it again.
