3D CARVING roughing and finish

Can somebody please explain to me how come I’m doing a 3-D carving and when I go to save the tool path this is what it’s saying…(see attached photo) I checked both the tools and one is tool number 4 and one is tool number 7 so I’m not understanding why this is saying that they’re both used the same tool number

If the tools are physically different tools then you can’t group them. If they are not the same you are probably getting the error because the “Group Where Possible” box is marked. Hope this helps…hope this is the problem.
