Unable to Edit Homepage Title

Hi everybody,

I am working on the most recent version of WordPress with the Enfold theme on the website “https://humanconnections.org”

For a reason I can’t understand, the title that appears when one searches “Human Connections” in google is “Human Connections{:}” as seen here:

I try to edit the SEO title, but even when I edit the title of “homepage” (https://humanconnections.org/homepage) it doesn’t change the information of https://humanconnections.org and the problem persists. Any thoughts on how I might be able to remove the {:} from our title on google?

Thank you,

Alex
