Problem with dynamesh substraction

Hi everyone

I am starting with Zbrush with a few tutorials, and I have come to a dead point pretty soon. The point is that i am starting with dynamesh subtractions, and everything is OK when I do one, but when I try to make a second substraction from a piece of dynamesh geometry, it adds random geometry in other parts of the dynameshed geo.
Please give me a hand cause I am really interested in learning and this problem is being very discouraging and a real pain.

Thank you all!!!

Make sure you are following those steps precisely.

You can dynamesh subtact by holding down alt with an insert brush (easy), or by merging one active dynamesh subtool onto another as a negative mesh. In the second case, the Target subtool must be active and merged down on top of the negative subtool. The target mesh must also be of higher polygon count than the subtractive mesh.

This “The target mesh must also be of higher polygon count than the subtractive mesh.”

Thank you so much!
