My Content and Settings button is not visible for guests

Dear WPDiscuz team, 

As the title suggests, “My Content and Settings” button is not visible for guests, although it is toggled to ON in the plugin’s settings.?
I am not implementing users subscription on my website, and would like to allow guests to delete their comments. You may check an example page?here.

I’ve tested it after logging out of my username, tried incognito mode and accessing from a mobile device. The button is not visible. I would also to confirm that I did not use any CSS code to manipulate anything else related to WPDiscuz plugin.

I also tried to post on your official message board, but my post is not getting approved for some reason, therefore trying to reach out to you guys here as well.
Your support as to how to resolve this issue is highly appreciated.

Thank you and kind regards,
