UniGetUI Version

3.1.0 beta 2

Windows version, edition and architecture

Windows 11 Pro

Describe your issue

After UniGetUI has found updates, pressing the refresh button to check for any new updates also triggers the "Updates found!" to appear, which doesn't appear to make sense because checking for updates has just begun. Once the refresh has finished, the notification appears a second time.

Steps to reproduce the issue

1. Launch UniGetUI
2. Wait for updates to be checked (some updates might need to be available to trigger the bug)
3. After the notification for found updates disappears, press the refresh updates button.
4. Notification appears immediately.
5. Wait for updates to be checked.
6. Notification appears again.
