"Include this contributor in browse lists" and Role Option: "Show role title in contributor list": How These Work?

I want to exclude translator from showing on the contributors list or at least to indicate “Translator” role next to the contributor’s name. I’d like it to work on both the article landing page and issue articles listing.

On the Edit Contributor page I cleared “Include this contributor in browse lists” and I also selected “Show role title in contributor list” in the “Translator” role option.

These only resulted in showing the “Translator” role name on the issue articles list next to the contributor name. No change is visible on the article landing page.

Are these expected results of those options settings?

I use OJS
