Marketpress Grid "Add to Cart" button

I have installed the Marketpress grid plugin, and made some “minor” changes to the css so the boxes were a little longer and spaced further apart. Now the uppermost left box has a weird placement of the “Add to Cart” button. It is to the right of the price with no spacing. I have tried removing and replacing this product but it continues to be a problem with only this box. I am using the Photocrati theme.

Here is the css:

#content .grid div.mp_product_meta{

clear:both;

background:none;

padding:0;

margin-right:0;

}

#content .grid h2.mp_product_name {

padding-bottom:10px;

margin: 0;

}

#content .grid .product, #maincontent .grid .product{

border:2px solid #000000;

background:#c2ab90;

clear:none;

float:left;

overflow:hidden;

margin:20px 20px 20px 20px;

padding:30px;

width:165px;

min-height:325px;

}

#content .grid input.mp_button_addcart{margin:10;}

#content .grid span.mp_product_price{font-size:14px;}

I have a picture if that would help. Any suggestions?

Thanks.
