deleting topology

hello ,

I made topology on eyes and in the centre of te face
I saved my sculpt as tool and The next day load the tool.

Now I try to delete the bad topology.My workflow is I use shift and click to select the topology.After selecting the topology I use alt and click to delete the topology.

The problem is after deleting the topology( red circles) the orange lines are still visible

on the sculpt.After deleting the topology I saved my sculpt as tool and reload the tool

and still the orange lines are visible.

How can I delete orange lines,why are the orange lines still visible ?

Regards ,

Tommy
