PHP8 warning on old HikaMarket version

hi
in this path:
JROOT/administrator/components/com_hikamarket/classes/category.php line:532
i see a php code maybe has problem please look at that. you write this code:
$where = ' WHERE (' . implode($where,') AND ('). ')';
but it seems it must :
$where = ' WHERE (' . implode(') AND (', $where). ')';
can you check it?
thank you.
