I found two problems with condition  on row 1418


   if($opt['limit']==1 || $opt['limit']=='first'){
                            $opt['limit'] = 'first';
                            $limitstr = 1;
                        }else{
                            $limitstr = $opt['limit'];
                        }

first: 
$opt['limit'] = 'first'; is forced to set to 'first' when you  limiting query 
to 1
but its used late as offset for array_splice.
                            $limitLength = explode(',', $opt['limit']);
                            if(isset($limitLength[1])){
                                array_splice($limitModelStr, $limitLength[1]);
                            }else{
                                array_splice($limitModelStr, $limitLength[0]);
                            }

second issue:
when you use limit range like "1,2", its converted to integer, so you get  same 
issue.
