how do I make these titles bold print?

Please let me know how to make the titles of my posts appear in bold print. I noticed that the majority of the posts have the titles in heavy black bold but mine are just regular even if I hit the B button. Thanks in advance 😁✨

The bold print goes away once you view the thread. So you know which ones you haven't read.  Yours aren't bold because you read them when you created them.
