Facebook avatars not displaying

First of all please let me say what a great plugin WPDiscuz is. Previously I had Facebook Comments installed on my website, but since August the comments were no longer being imported into Wordpress.

I have only one problem with WPDiscuz and that is related to Facebook avatars which are not displaying in the comments section. If I check the comments in the Wordpress admin all of the Facebook avatars are present.

I am using WPDiscuz im combination with WP Social Login, and many users are using their Facebook, Google+, Twitter, and other accounts to login.

Therefore I would have expected that all avatars from such social account logins should have been captured by WPDiscuz.

I cannot find any possibility to control avatars in the settings.

Hoping there is a solution to this issue.

Please advise.
