That is a shortcode that the plugin puts in on-the-fly to correct potential issues with some WP functions that insert line breaks. When it is unparsed like that, it is the result of the way the forms are being called/displayed.
You can overcome this by filtering out the wpmem_txt shortcode using the method described here:

Hi tried the above method as it is described in the link.
But i can still see that shortcut code and even the code snippet after i paste it in my themes function.php.
The theme which I am using uses the template builder and I am placing the shortcut code of login and registration form into the template builder not in the default WP text editor.
If i am placing the shortcut code of login and registration form into the default text editor then everything works fine i dont even need the code snippet you shared.
Why is this happening?
Please help.
