sc-dash appearance behind Page Title

Good evening everyone,

I’m Kevin, living in the Netherlands and new to this forum.

As a entrepreneur I love developing new things and solve problems.

Well, I apparently developed a new problem which I can’t solve.
I didn’t change anything to the title of the site but somehow there appeared sc-dash next to my Cargo Support in the page title.

I am working with the Astra theme and the only 2 plugins I’m using are Contact Form 7
and Premium SEO Pack.

I already searched the forum but couldn’t find anything.
Can someone please help me out because it is really annoying me.

The page I need help with: [log in to see the link]
