Plugin breaks image alignments

Hi,

after installing the plugin, images inside posts lose their original alignment. It looks like all images are being placed left. You can see an example on this post:

Additionally on my ‘team’ page, where i use widgets on pages, the layout breaks completely.

Can you help with these issues? Is it just a css issue or something else?
