Below is my SharePoint list.

Below is my flow.

1. But when I run today (19th March 2024), the flow deleted both item with title A and B. Supposedly item with title A only. What did I do wrong?
2. Which one is better expression? My SharePoint local time is GMT+8.
Date lt '@{utcNow()}'
Date lt '@{addMinutes(utcNow(), 480)}'
