LibreOffice AppArmor messages in Linux

I use LibreOffice into UbuntuStudio 16.04.3 LTS.

I downloaded and Installed last version of LibreOffice (6.0.1.1) and now I get a lot of AppArmor messages each time I started any of the LibreOffice internal components (Writer, Calc, Impress, etc).

What’s wrong here?

Is it meaning something dangerous?

How can I fix it?
