Personal statement job info not on CV

In my personal statement I talk (briefly, like 2-3 sentences) about a job I held in undergrad. I didn't include the job under ERAS's Work experience bc it just seemed like resume padding. However, I do think it adds a necessary wrinkle to my statement. Can anyone think of why this might be a bad thing? Such is the fear MS4's live in...I'm worried they may think I'm not being truthful or something.
