Physical presence calculator error when printing - showing 0 days credit when before printing everything is fine

[acrobatmoon]

I spent a good chunk of a few days entering all my days of physical presence and absences, and showed I had more than enough days to be eligible. However, when I go to print, all of the sudden the dates are missing, and it says I'm ineligible.

Is this a normal bug? Did I enter too many dates? I had lots of same-day trips across the border. Is there a max number?

Don't know how to delete this message. I had the date I was to submit the application in the future, which was giving me the error. All good on my end.
