Data Not Passing Through/Saving

My multistep form doesn’t pass/hold on to the data from some of my steps/form fields. I have a form that has 8 steps about 120 total fields. Only a few of the form fields actually save and pass the data along, it seems like the first few steps work (1-4) but the rest don’t.

I’m on the latest version of the plugin. The other thing I noticed too was when I hit the next button I see the data gets blanked out, then it moves on to the next step. It doesn’t seem to be browser specific.
