Bug? - When running an anonymus poll, the voter's name appears in the notification box...

Giuseppe Public Seen by 27

I observed a bug on my running loomio instance.
I created an annonymus poll. But when people are voting, it occurs, that "Annonymus" has voted.
So far so good - but when I look in the upper right corner in the notifications, I see the icon of the user that is declared as "annonymus".
As a result - the poll is not annonymus anymore :D

Is this a bug? How can I fix this? Can I get help?

Here a Screenshot of the observed Bug - It is in German, but you can see the word " Anonym" and on the left the Icon of the person who give the vote...
