Costing split of FG material

Dears

We have done costing of a finished material and in the costing hierarchy (in 'costing structure' area, left side of the screen) two material are shown with symbol 'costing' but in fact they are raw materials only.

ON checking the material master, 'do not cost' indicator was not checked and we have corrected it now.

But even after that, if we recost the FG material, the same symbol of 'costing' is appearing against these two materials. Since these are raw materials, the symbol of raw material (with a bin picture) is not appearing.

What we are doing wrong here ?

Please help.
