If you ever find yourself in a situation where one person has multiple profiles in the same module, here’s what you can do.
Step 1: Remove the duplicate profile from your organization. Note that this will remove data from the profile, so you might want to copy (manually) any data from that profile into the one that will be kept.
Step 2: Have the member merge their profiles. This is something that only the member can do, since they may be using that profile with another organization.
