I am using 5.0.12 (also applies to 5.0.13) and noticed that in the back end dash board the comments are wrongly attributed in the main display. THis is relatively minor but will need addressing sometime.
The comments are correctly attributed in the system and display correctly on the 'comments screen.
On the dashboard (comments) it show the image and name of the person who created the blog post and the comment that was last posted by the third party. IT should show the image and name of the person who posted the comment.
In the first image (dashboard) attached the owner of the blog post is shown as having made the comment, but the comment was not theirs, but of another person. As shown in image 2 the comment is correct attributed in the Comments screen.
