Dear Nick,
Good day!!
Apologies for the inconvenience caused and please don’t worry, let’s work together on your concern and move towards a resolution path.
I understand your concern and I would like to convey that I have performed the exact steps at my end, where I am able to reproduce the same problem as explained. So, I have tested the behavior in the different lists with the same steps, where I noticed the same behavior.
Moreover, I believe the behavior we are observing is not an expected behavior and there won’t be any flow create created in our Power Automate page, where it should be a bug.
In this situation, I believe the problem should be further investigated by related development team via collecting HAR logs because there is no any related service incident reported at the Microsoft Service Health dashboard.
I do feel regret for not resolving the problem and redirecting you to the related development team but the fix to your concern can be find out through the HAR logs and suggest you raise a support ticket from the Office 365 admin center, where the related team will investigate the problem further by collecting the HAR logs.

Note: To create a support ticket, you need to have admin privileges and if you aren’t admin of your Office 365 organization, please contact the admin of creating a new ticket.
Appreciate your patience and understanding. Have a great day!!
Best Regards,
Sophia
