Problems with layout in Nucleare (theme)

wordlas

The comment title is placed on top of the comment box. Furthermore, changing the position from bottom (B) to the other locations of the CAPTCHA do not even appear in the theme.

Tried to change the CSS of Nucleare but it didn't help. Does this plugin has its own CSS?
