Question about caseload

I am running into a problem with the IEP coordinator. In September she printed me and the other social worker's office caseload. Since then, my caseload has grown from 29 to 39. 🫠 But the main issue is, she's adding kids onto my caseload who have service minutes attached to a plan that I didn't know about.

For example, she added a 504 student to my caseload about 2 weeks ago. I asked if he just got a 504 and she said no, mom told them at PT conferences he had one.. That confused me because I thought they had a running file of every student in the building with a 504 or IEP. Then she added another 504 student recently and I looked in his file, and saw that he's supposed to receive 30 minutes of counseling services a week. And his 504 plan review is next week. I have never met him, and he wasn't on my official caseload.

Has anyone experienced this issue at their school? I know sometimes new kids can get added, but this seems like an oversight almost.
