Visual Composer plugin have changed mechanism on how margins are applied.
This may cause margin changes for few users and now it is necessary to adjust margins manually. This is unavoidable.

Some comments from plugin comment section

** We have changed mechanism on how margins are applied – it was a must have task for a long time already and need to be addressed. margin changes for few users and now it is necessary to adjust margins manually.

** We constantly receive requests including margin and padding mechanism – this is why we also felt that it has to be done. Of course this bring up additional efforts in aligning with new standards, yet it does not affect all users. We understand your frustration and of course we will pay proper attention to any future changes to ensure backward compatibility.

** In our latest major update we made a huge margin refactor which has to be done for a long time already so this may affect margins and positions in some cases. Right now you will need to manually adjust margins and paddings. But I can assure you that new mechanism is the proper way of applying margins and paddings and with it you will have more control over elements and layouts.
