The Partial release message (which does not really tell you anything) overwrites the final print time on the LCD, which is a real shame. So I removed the message.

Marlin/Marlin_main.cpp

 #endif

               disable_e2();
             }
           #endif 
-          LCD_MESSAGEPGM(MSG_PART_RELEASE);
         }
       }
       break;
     {
       if(code_seen('S')) 
       {
-        feedmultiply = code_value() ;
+        feedmultiply = code_value() ;
         feedmultiplychanged = true;
       }
     }
