@horism,
Use the CSS code below:
#wpdcom .wpd-comment .wpd-comment-right {
padding-bottom: 0px;
}
#wpdcom .wpd-comment-text p {
margin-top: 0px ;
}
Put the code in the Top Admin Bar > Customize > Additional CSS > "Additional CSS" textarea, save it, delete all caches and check again.
The red marked value can be changed if it's necessary.
Please don't forget to press Ctrl+F5 (twice) on the frontend before checking.
