In the Plugin Configuration, role name is used instead of Role Title. Therefore, when I've viewing the list in non-English language, the list is displaying roles in English instead of localized title. (See attached when viewing in Japanese)
To reproduce:
1. Control Panel -> Plugins Configuration
2. Select any Portlet from the list
3. Elements in "Name" columns are all in English
Fix:
portal-web/docroot/html/portlet/enterprise_admin/edit_plugin.jsp
Line #123
<liferay-ui:search-container-column-text
name="name"
property="name" <-- change this to value="<%= role.getTitle(locale) %>"/>
