Testing Roth setup and issues...

I have several issues I can't seem to understand what is causing it:
1.  One employee looks fine on the pr140 csv file with their 401k ee cont amt pre and post tax and their er cont amt pre and post tax.

On the pr140 pdf their pre tax ee cont amt or pre tax er cont amt are not on it at all. What's up with that?

2. One employee we maxed out their check so it would max out their 401k ee cont amt, 401k er cont amt, but their 401k ER cont amt didn't show up at all on the pr140. It didn't do this on all ee's that maxed out just this one.

3. Another employee, she is signed up for 403B pre and 403B Roth post tax contributions and her Roth post tax ee cont amt and Roth post tax er cont amt's came out fine...nothing for the pre tax.  I do have the pre tax plan as the default plan on the plan.

My set up on bn15 is we kept the same 401k and 403b benefit plans but created 4 new deduction codes: 401k roth, 401k er match roth, 403b roth, and 403b er match roth.

In production, on the BN15.1 vesting comp tab, we have the pay class blank and the apply max limit as N. Could this be an issue?  this is how I left it in test since that's how it's set up in prod.

HELP!!!
