Why does LaTex insert a line between list items?

Question

I didn't add a line between these items but it automatically outputs one. Why is this so and how could I prevent this?

Strange thing was, I had the same amount of items before and there was no extra space. Suddenly it changed after I altered the items. I tried making the item list shorter, thinking it was a spacing error, but that didn't resolve it. I can't figure it out for the life of me.

Welcome to tex.sx. The blank line is a consequence of your wrapping braces around the text of that item, and having the bad luck that the text fills the full line. So the physical end of line adds a space that has to go to the next line, which thus looks empty. You can add a % at the end of that input line, which will get rid of the "input space", but may result in a warning or error. (I haven't tested this; no time just now.) — barbara beeton, Nov 17 '22 at 18:30
There are lots of unwanted spaces in the definitions of several macros in your example. → How to avoid unwanted spaces in the output or https://tex.stackexchange.com/questions/7453/what-is-the-use-of-percent-signs-at-the-end-of-lines-why-is-my-macro-creat — cabohah, Nov 17 '22 at 18:50

The item almost exactly fills the space available for the line and the \resumeItem definition adds a space after #1 that starts a new line.

To correct the issue use

\newcommand{\resumeItem}[1]{\item\small#1\vspace{-2pt}}

IMPORTANT please see Why is my macro creating extra space? to correct the other command definitions (by adding %}
