How to remove subsection extra spacing

I have this extra space appearing between the text and the subsection. Not sure how to remove it. It happens just in this spot.

PS: I just noticed that when using these macros I created in one of the pictures captions that precedes this section, the gap in question is increased.

renewcommand{suggestadd}[1]{%
textcolor{Green}{#1}%
}

renewcommand{suggestremove}[1]{%
textcolor{red}{st{#1}}%
}
