Form cell alignment missing after plugin update

here I mentioned my code, please let me know why the sudden change happened in visual alignment.

<div class="row clearfix">
<div class="col-6">[text* your-name placeholder "Name"]</div>
<div class="col-6">[email* email placeholder "Email"] </div>
<div class="col-6">[tel* number placeholder "Mobile (with Country & City Code)"]</div>
<div class="col-6">[text* country placeholder "Country of residence"]</div> 
<div class="col-6">[text* city placeholder "City"] </div> 
<div class="col-12">[textarea message placeholder "Message"] </div>
<div class="col-2">[captchac captcha-778 size:s fg:#ffffff bg:#000000] [captchar captcha-778 4/4]</div>

<br><br><br>
<div class="col-12">[submit "Send"]</div>
