# significance of pvalue for logistic regression [duplicate]

I'm trying to understand how to interpret the significance of logistic regression

If I use the standard iris dataset, the Petal Length is a significant predictor for the Setosa classification. If I use JMP, I can see that the logistic regression is essentially a perfect classifier for the setosa class.

The whole model test also confirms its significance.

why is the pvalue shown as insignificant in the parameter estimates table for this factor "PetalLength"?
