Code128 and Code128B renders the same barcode

I need to set a code128 barcode but it renders in code128B.

Ex.:

     <subform w="576pt" h="756pt">

         <field name="Code128BarCode3" y="6.35mm" x="6.35mm" w="190.5mm" h="13.594mm">

            <ui>

               <barcode type="code128" wideNarrowRatio="fixed" textLocation="above" dataLength="49"/>

            </ui>

            <font typeface="Courier New" size="8pt"/>

            <value>

               <text>905500000000009020152T9560367596351ET3HT000000HB0</text>

            </value>

         </field>

         <?templateDesigner expand 1?>

         <field name="Code128BBarCode1" y="19.05mm" x="6.35mm" w="190.5mm" h="13.594mm">

            <ui>

               <barcode type="code128B" wideNarrowRatio="fixed" checksum="auto" dataLength="49"/>

            </ui>

            <font typeface="Courier New"/>

            <value>

               <text>905500000000009020152T9560367596351ET3HT000000HB0</text>

            </value>

         </field>

      </subform>

But an online web app renders:
