Latest plugin update possibly broke wordpress

Hi,

It seems that the recent plugin update has broken the whole wordpress functionality.
The line 1-3 in the class.paytm.php is causing itself to appear in every network call response from any API. This is causing ill behavior in whole website. Please, check this and fix it quickly. I think the line 1-3 need to be removed:

<style type="text/css">
        #woocommerce_paytm_iswebhook{display: none;}
</style>

You can API response for any api in wordpress to see that the above line is appearing everywhere, be is normal content or even a Json content.
