Custom Race: Skill

Anyone know why the following would not add the Medicine skill to a character when attached to a custom race as a racial trait for 5E?

You gain proficiency with the Medicine skill.

I can't tell what's wrong with it. I've checked other races and watched Grieg's videos. I believe the syntax is consistent with what Unity is expecting. I've tried with and without the skill link in the trait. I've tried naming the trait Skill, Skills, and something campaign specific. No dice for any combination.

Try "You have proficiency in the Medicine skill"

MOD: Moved to 5e forum

This is just what I was looking for:
