In the frontend editor, the text justify button is not working. You can check it by logging in and trying to edit the teacher bio found under Dashboard -> Profile settings.
This is obviously a bug and I am surprised I am not getting any help with this.
Have you tested using a different template? I cannot seem to replicate your issue on my testbed.
If I login to the site using the provided info above and then go to the teacher's dashboard the text alignment does not work. Several users also are experiencing this issue. Since you and I are logging in with the same user account we should experience the same thing. Here is the link, and I cannot change the bio text to center. https://modernmysticmysteryschool.com/teach/guruauthor/authorprofile/ Also the other text features, underlining, lists, etc are working fine. It is only the text alignment dropdown.

Could you take a backup of your site and install latest version for Guru component?
