Journal Entry Not Saving in Free Account

Hi, opened a free account 2 days ago. I created few purchase order, Purchase Invoice. But when I click on Payment Entry from Purchase Invoice page, then it opens up like this (All blank)

Then I added manually the data

But when I click on Save. Then it throws up double empty account without saving.

I tested, it seems fine. I looks like I’m missing some settings.

Can anyone point out where I went wrong ?

Fixed. Refresh and try again.
