Iam trying a lip sync and my character doesnt lets me change the value of the shape key , i mean it does changed when i click and drag but it gets back to 0 again .
Here is the file :https://www.dropbox.com/s/j8vkahgn2lrco0v/error%20mouth.blend?dl=0
plz let me know the mistake iam doing in here
EDIT : So it turns out that when i double to open the file , shape key doesnt turn orange ( while changing the value ) . But when i open blender and import the file in it then it turns orange while changing the value .
Is it some kind of bug or what ??
