Icôns of Libre Office apps

Hello,
Any document created with Libre Office apps icôn is a cornered white sheet. I would like to have one icôn for each of them, and not this white page. How to do it?
Under Mac 10.8.5
Libre Office v.4.3.3.2
Thank you for your help.
Pierre

Go to Google Store. There are separate apps there.
