Unmatching title in BuddyPress

My site has BuddyPress enabled and uses the theme BuddyPress Corporate.

I recently found out that for every page, the title is shown as 'domain.tld - Blog', irrespective of the page's name.

However, the title seems to be properly matching with BuddyPress pages, like 'domain.tld - Members Directory' for BuddyPress Members Page.

When I checked with the title tag in my file manager, the code seems to be fine.

Why is this happening and how do I fix it?
