Should I concern signs from the model result using Weight of Evident(WOE)?

Hi,

I ran a logistic regression model with only 5 inputs using WOE and found all 5 inputs are significant and have positive signs . However, when I ran bivariate model, some inputs have negative relationship with target variable. Should I worry about the sign issue? Thank you.

No worry. It is normal.
