IWEDIT added to IWREGION creates additional DIV

[Moskwa]

Hello,
I have a problem with IWEDIT added to IWRegion. Intraweb generates that code :

Code:

<div aria-label="Wybierz skonto" class="btn-group" id="IWREGION9_FRAFRAME2" role="group">
  <label class="btn btn-outline-primary" for="BUTTON_0_FRAFRAME2" id="IWLABEL_0_FRAFRAME2"><span style="font-size:18px">zgodnie</span><br><span style="font-size:14px">z umową</span></label>
  <div>
    <input autocomplete="off" class="IWEDIT1_FRAFRAME2CSS" id="IWEDIT1_FRAFRAME2" name="IWEDIT1_FRAFRAME2" spellcheck="false" type="text" value="IWEdit1"> 
  </div>
</div>

where before IWEDIT1  I get additional DIV

In design I have only IWREGION9 and IWEDIT1 in it:

   

any idea why I get additional DIV ?
