st: Marginal effects after biprobit

Dear Colleagues,
I run a biprobit regression and all variables are significant but I found
that the sign of the independent variables changes sometimes when I do the
different combinations for the marginal effects after biprobit regression,
i.e. (p11), (p10), (p01) and (p00).
So could this be a problem or what. Any idea....
Any participation is highly appreciated 
Thanks in advance
