Incomplete "filter by" menu problem in Mail on macOS Sierra

Hi all,

I am experiencing something what I believe to be an accessibility bug in the new messages list filter feature of the Mail app on macOS Sierra.

If I enable the filter by ticking the checkbox left of the messages table (or by pressing Command + L) and then press the button located just one more step to the left of the checkbox, to open the "filter by" menu, it normally shows 11 items to choose from. However, whenever I close the menu and open it again, VoiceOver announces and allows me to choose only from two items: only the mail with attachments and only the mail from VIP.

The only way to have VoiceOver letting me to choose from all the 11 items again I found is by closing the main window of the Mail app and opening it again (Command + number 0 through 5), or by relaunching the app completely.

Has anyone found another workaround for this, or is anyone else experiencing the same at all?

Thanks for your replies

Adam
