I have a problem to set placement.
First, if inline position is set, buttons are not displayed by default in articles and categories.
Why I must define components where to display ?
Second, when I click inside the field to set the display locations, all content disappear.
Look a image 1
It seems there's a problem with the css class "animated".
If the attribute "animation-fill-mode" is on, then all content is hidden.
Like you can see on image 2, all content reappears if this attribute is off.
