Push 2 same events at once and deleted tag still shows up

Track Scroll JS code in Wordpress snippet:
The same event appeared 2 times at once but it only happens when I access via phone or other devices.

The Scroll Depth event is from matomo tag manager but it’s been deleted:
The Scroll Depth event was deleted but it still shows up when access from Firefox.

Probably, the device does still have the old Container in the Cache. try to use Browser “Private” Mode or delete the browser cache before testing.
