Problems with organizing objects on a slide

Hi!

We are trying to place some buttons on a slide, but the result looks different from what we see in editing mode (different scale, slightly reordered)

How it looks in editing mode: http://vmestemedia.ru/wp-content/uploads/2016/03/AdminPanel.png (this is not what we are trying to achieve, but still illustrates the issue)
How it looks in preview mode: http://vmestemedia.ru/wp-content/uploads/2016/03/PreviewAdminPanel.png
How it looks on the website: http://vmestemedia.ru/wp-content/uploads/2016/03/Chrome.png

What should we do to fix that?
