I installed Libre Fresh 4.4.2 (using Yosemite) and there are no icons on any of the toolbars. I then “replaced” it with Libre Still 4.3.6 and the toolbar icons are there. Am I doing something wrong, or missing something?
Looks like you found a bug!
May I propose to file a bug report here: https://bugs.documentfoundation.org/
Please note that for selecting the LibO version you need to scroll the Version list up
