problem with stepwiseglm selected features pvalues

I'm using the following line for stepwiseglm

glm_model = stepwiseglm(chosen_features,idx,'constant','Distribution','binomial','upper','linear','PEnter',0.1, 'PRemove',0.15,'Criterion','aic');

I've set the Penter and Premove so that I can choose the pertinent features, however when the model is trained the feature pvalues are not within range, in fact I have PVALUES LIKE 0.3 in my model.

The only other thing I can think of is that there is 70% to 30% prevalence between my o and 1 classes.

Anyone has an idea?
