Hi,

Here is a quick and dirty patch for this. Just modify the file 
"[extension_dir]/view/class.tx_ttproducts_list_view.php"
and add

$queryParts["GROUPBY"]="products.uid";

on line 480.
Don´t forget to add 
"plugin.tt_products.conf.tt_products_cat.ALL.language.type = table" to your 
TS.
This worked perfectly for me.
