transpose tool and layer questions

hello everyone,
I have two questions here.

1.Why the transpose mask tool is so difficult to use in 4R2. When I drag mouse the mask will not complete most times, sometimes can be successfully when I shake my mouse repeatedly after draging. Didn’t I set up correctly?

2.How to avoid the material and color information is recorded in layer, because when I’m baking it always show some dirty effects on the model.

thx
