Share point Power Automate

thobenjo This is not a power automate, it is a Rules feature in SharePoint Online/Microsoft Lists.

I just tried creating a similar rule and it is working properly: 

So, I am unable to reproduce this issue. Can you try & check these:

1. Try creating similar rule in another test list in same site as well as different site.
2. Can you check if there is any error in browser developer console?

Let us know what you find by trying above two suggestions?

If nothing works, you have to raise support ticket with Microsoft directly: Get M365 support - online support
