When I try to use "/execute @r[name=]" it says that no entity's were found. I've gotten this to happen multiple times in multiple worlds. Luckily, it's not all execute commands. Only @r[name=] for some reason.

the following image was taken of a command blocks command that failed. Even though multiple of the entity that it was supposed to effect was in the world.

Edit: I’ve found new information that it is not just with /execute. And it has been around for over a year. I don’t even understand how a bug like that could be around for over a year.
