Names not showing in Styles & Formating list

Using LO on Mac OS X El Capitan.

In the Styles and Formatting pallet the Title, Subtitle, and Heading1 items are present but the names are not.
There is a blank space that I can click on and it functions properly.
When I click Modify, the Organizer shows the correct name.

All other names in the list are visible.

Can anyone reproduce this? (or is it my system that is at fault?)
