I assume you want balance to adapt to that transaction. I have faced the same issue and figured out that there is time settings to fix this.
My solution was:
On Settings, go Transactions tab, then on Transaction/Budget section, check "Use 'Time' in transaction recording/reporting" box. That is fixed that issue for me and i hope would fix it for you too.
But beware, every transactions you have at that time will have the time of "00:00:00". I had few hundred of transactions when i figured the time setting. I must say it was both easy and overwhelming for me to edit all those transactions.
