Please help me with the problems in CATIA (surface design)

I have faced a big problem in CATIA. When I try to use every commands in CATIA the feature in the specification tree always show different one. For example, in the attach file, I use an extrude command when I finish doing this it shows up a surface in the specification tree with a red flash which cannot be modified.
How could I fix this? Please help me
