Welcome back to the Community. It's important you're able to see the journal entry on the supplier's account. I'll be happy to look into this so you can get back to doing what you enjoy.
Normally, when you create a journal entry which affects the Accounts Payable on that supplier, the entry should appear on the supplier's account. Were the transactions on the journal entry hitting the supplier's Accounts Payable? The reason I ask is that I'm not able to clearly see the transactions in the screenshots you provided. You can also view the journal entries by running an AP Aging Detail Report by clicking Reports from your left navigation menu and entering the report name in the search field.
If you're unable to view the journal entries, I recommend giving your browser a quick clean by clearing cache and cookies. Doing this will help fix most issues the site may be having. Here's an article which shows you how to do that: How to clear Cache and Cookies. Give this a try and let me know how you make out. I'll be here in case you need further assistance.
