ECS UI Bug in Update Service from the Task Definition

Hi Guys.
Please check out a bug in the UI that I did not find any place to update about.
When going into a task-definitions -> choosing one task definition -> actions -> update service, and then the service can't be changed and "stuck" on the default one:


Can you please check?

Thanks

Reproduce the issue through Task definitions → choose a task definition → Actions → Update service, using the screenshot and reported default-service behavior as the starting point. Investigate why the service selection cannot be changed; done means the intended service can be selected and the update flow proceeds normally.
