Probably, this is because the low and high groups are interchanged.
The threefold decomposition depends on this (have a look at the
formulas in the helpfile).
Say, your oaxaca command is
. oaxaca est1 est2, tf
Then try
. oaxaca est1 est2, tf asis
If it does not change, type
. oaxaca est2 est2, tf asis
Or, alternatively, change the coding of the by-variable in the oaxaca2 call.
