Group loops problems r6 version

Hi to everyone!
I’m new to Zbrush and I started using the r6 version. I’m realising a woman bust and I need to create a group of loop on her face to determinate the shape of her eyes and mouth. Even if my mesh is selected under Geometry, EdgeLoop I can’t select things like GroupLoops, Triangles, Gpolish and so on…Can someone tell me why this happens?

Also in the new r6 version I can’t find the del lower resolution button

Again I m new to Zbrush so I thank you in advance for your help!

tool.geometry.delete lower

you need to delete your lower to use the functions you have grayed out.
