Editing info in summary section under your name on profile

I have multiple employers listed under my Work Info. However, I want only my main employer to be listed in the little info summary under my name on my profile. Just to clarify, I'm talking about the section that reads something like this:

JANE DOE
Position at Company Studies at University Lives in City, State Knows English, Français From City, State Born on 1 Jan

Currently it's displaying my most recent employer, which is just a side business I'm involved in. How do I change it back to my main employer?

I'd appreciate the help! Thanks!
