Speed dial "Don't show again" won't work.

A Former User

I'm using Opera 71.0.3770.198 and I'm having a problem where the "Don't show again" button from the speed dial is not working anymore.

I like the speed dial, to have the most used websites I go, but sometimes other sites are automatically added on the speed dial, and I would like to have the ability to remove some of those sites to be able to customize.
But when trying to remove a website from the speed dial with this "Don't show again" button, it doesn't do anything. The site stays there, and my only options are to leave it there, or disable speed dial.

This is the button (sorry for pt-br translation):
