No longer alligning left or right

Hello,

I love this plugin but recently it has stopped aligning left or right, and will only display as a rectangle taking up the full width of the page. See below for an example of a box that should be aligned right.

Do you have any suggestions for why it might be doing this? Could it be the recent update and if so could I roll it back?

Thanks
