Author archives/profile issue

I reported this issue earlier but it’s not resolved. The plugin seems to be breaking up author accounts on our website.

For example, these are the same user, however, the posts have been split up between a contributor account and a new random guest account:

https://www.advancedsciencenews.com/author/cap-vcorless/ (some of the content from vcorless has been designated as a “guest user” after installing the app)

https://www.advancedsciencenews.com/author/vcorless/ (original user)

Content in both these lists are from the same author, but they’re not being displayed as such. This happened after installing the app. Have tried modifying the apps settings under “maintenance” but no change.
