This layout problems are happening because your Joomla Template was already stylizing the Virtuemart pages (because it was Joomla Virtuemart templates). The most ideal way to eliminate the joomla template's stylization and let the FlexibleMart to style the virtuemart pages. Anyway:

open this CSS file:

and add this CSS rule (to the bottom of the file):
div.vmAddtoCart{height:auto;}
input.addtocart_button{margin-left:10px; display:inline-block;height:25px;}
the result will be:
