Shaping Trouble when using M4 base

in New Users
There's a "shape" cateloge in M4++, seems to shape the emote of the character. But I double clicked on those "inject shape" to shape the emote (i,e, Lipspart, Mouthsmile), But nothing happened. How could I use those shaping ?

You inject the morphs and then go to the parameter sliders to actually do the adjustments
Found it! thank you so much for helping
