Insert multiple rows with three single selects and one multiple select on each row

Every time the user clicks + a new row is added and when the user clicks x a new row is deleted user interface. There are four dropdowns. Month(single select) , Year(single select) , Main reason (single select), Secondary reason(multiple select). Main and secondary have the same id because they need to be inserted in the same column in database table structure

With the current code,only the first row inserted in database is correct (see second image). Everything else is messed up

PHP

if (isset($_POST[‘acute_id’]) && !empty($_POST[‘month_acute’]) && !empty($_POST[‘year_acute’]) ){

                array_push ($variations_cols, $db -> quoteName ('update_id') . ',' . $db -> quoteName ('acute_id')
                    . ',' . $db -> quoteName ('month_acute'). ',' . $db -> quoteName ('year_acute'));
                
                
                $unique_genes = array_unique ($_POST['acute_id'], SORT_NUMERIC); //remove duplicate genes
                $unique_keys  = array_keys ($unique_genes); // keys of unique values
                
            
                for ($i = 0; $i < count ($unique_genes); $i ++){
                    
                        array_push ($variations_vals, $db -> quote ($updated_id) . ',' . $db -> quote ($_POST['acute_id'][$i])
                            . ',' . $db -> quote ($_POST['month_acute'][$i]). ',' . $db -> quote ($_POST['year_acute'][$i]) );


                }

                insertIntoTable ($db, "patient_has_ac2", $variations_cols, $variations_vals);
            }
