Different name displayed under author

Dear Alx,

Thank you so much for creating this theme. It is by far one of the best themes I have ever used, for many reasons.

Today I wish to inquire about an issue I am having with my website. You see I recently changed my posting account under a seperate account name “DarrenW”, which is one of the author accounts I allocated myself to use.

Previously I used the admin account to post articles, of which was also called “DarrenW”, but after the change I changed it to “WWHCurrent Anime & Manga Society”

The author’s bio thing displayed at the bottom of each post is of the correct account, its just the portion which says “BY (author name) · Date” still refers to the old account.

Is there a way to rectify this?
