That why i dublicate code in default_grid.php and make it show as i want

<?php
echo "<a href='".$linkTarget."'>".$content->ad_adbrand." ".$content->ad_admodel."</a>";

?>
<?php
echo "<a href='".$linkTarget."'>".$content->ad_adbrandmoto." ".$content->ad_admodelmoto."</a>";

?>
<?php
echo "<a href='".$linkTarget."'>".$content->ad_adbrandkommers." ".$content->ad_admodelkommers."</a>";

?>

But problem is if i choosing one category and choose brand and model fields. Saving.
But If i choose wrong category and want change it. I changing another category and saving but in list i can see last category fields value. Like here prntscr.com/7cxh3i
