Miro Layers in an Org Chart

Hello, good morning, I am working on a MIRO Board, specifically with an Org Chart. The idea is to keep adding layers by Roles, that is, so that every time a user selects a specific layer, all the people in the organization with the same Role are shown and selected. The other day it was working fine, but since yesterday, every time I try to move a contact to a specific layer, it modifies the organizational chart, either deleting contacts from the branch below the selected contact or moving other cards, and honestly, I don’t understand where the error is.
