You need to show a screenshot of the Purchase Invoice as that seems to where the problems is arising. After posting the Purchase Invoice the P&L Labels account should show 35.09
Your Purchase Invoice for Supplier - American Label - should have the Account = Labels.
This way your Accounts Payable would increase by 35.09 and P&L Labels would show 35.09
Then you would do the payment as per the first screenshot - Account = Accounts Payable.
This will reduce your Accounts Payable by 35.09.
In addition, under the BS Equity, that Suspense account shouldn’t exist. You need to click on the blue 1,500 and see what entry is causing that problem
Also, the Starting Balance Equity account shouldn’t exist either. Go to Reports - Starting Balances and compare those figures to the BS figures for your previous accounting system - they should match account by account.
