SELECTED DROP BOX SHOWS 2 VALUES FROM MYSQL DATABASE : Hey I am having some trouble with my dropdown menu values that I retrieve from my database. I see two values instead of one. 

         $con = mysqli_connect("localhost","root","") ;
    
         $myDB = mysqli_select_db($con, "test");
    
         $dbEnc = mysqli_set_charset($con, 'utf8');
    
        
         $sqlSELECT = mysqli_query($con, 'SELECT class FROM disastergroups'); 
    
    <!DOCTYPE html>
    <html>
    <head>
    	<title>test</title>
    	<meta http-equiv="content-type"
    	content = "text/html; charset=utf-8"/>
         </head>
        <body>

    
                    

     <select name="test">
    <option value="">Select...</option>
    			<?php 
                         while ($row1 = mysqli_fetch_array($sqlSELECT)):
                 ;?>
     <option><?php echo implode("\t", $row1); ?></option>
     <?php endwhile;?>
     </select>

    <input type="submit" value="Submit Data">
    </body>
    </html>

The image below shows the duplicates in the dropdown menu... how do I fix this?
