Views filter taxonomy level

Hello
The module is very good, works to perfection, I am using taxomomy_menu with custom path, and path auto:
configuration:
Views taxonomymenu
views:
Type:term

Style: Unformatted
Row style: Fields

Arguments
Taxonomía: Term ID ( selected : Allow multiple terms per argument. and Allow multiple arguments to work together )
Taxonomía: Term ID depth modifier

Display Page :
Row
Patch : taxonomy/term/%
Style: Unformatted
Row style: Fields
Everything works perfectly, VERY GOOD module. I have a vocabulary
Vocabulary
TERM1
TERM1a
TERM1aa
TERM1ab
TERM2
TERM2a
TERM2aa
TERM2bb
TERM3
TERM4

Term1 link brings all nodes labeled with Term1 and sublevel this includes nodes which (Term1, Term1a, TERM1aa , TEM1ab)

Term1a link brings all nodes labeled with Term1a and sublevel this includes ( Term1a, TERM1aa , TEM1ab)

Someone could help me with the filter so that the link Term1, just bring nodes which Term1 and Term1a and not the third level TERM1aa and TERM1bb . As link Term1a, just bring Term1a and not the third level TERM1aa and TERM1bb

NOT find a way to make the filter so as to exclude bring nodes labeled which the third level. whether in all cases or only in certain terms.

Some idea forgiveness for my inglis.
