text input truncated in bootstrap modal ( codeigniter 4 )

I am using modal to make input text for update a field in CodeIgniter 4, but the text truncated into a smaller(narrower) text. The code in modal (inside sertifikat.php) is :

<div class="row">
   <div class = "mb-3 row">                                                
       <div class = "m-1 row">
         <label for="kode_ta">Kode TA</label>
         <div class = "col-sm-3">
            <input type="text" class="form-control" name="kode_ta" id="kode_ta" value=<?= $v->kode_ta; ?>>                                  
         </div>                
      </div>

     <div class="mb-3">
        <label for="sertifikat">Sertifikat</label><?= $v->sertifikat; ?>
        <input type="text" name="sertifikat" id="sertifikat" class="form-control" value=<?= $v->sertifikat; ?> required>       
     </div>
                                    
     <div class="modal-footer">
       <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Tutup</button>
       <button type="submit" class="btn btn-primary">Simpan</button>
     </div>
   </div>
 </div>

I have changed to use object model (protected $returnType = 'object';), but basiccaly the same with array mode, and the result is the same. When I trace, not all field inside the text field, below is the picture when I inspect it :

the value should be "Certified International personel assessor (cipa) oleh pt. quantum hrm international tahun 2020", but it show only "Certified" in bootstrap modal text field. When I run the program, it looks like this: sertifikat

Could anybody help me, please ?
