Reference Attributes are duplicated

Hi,

My Subtasks Folder has a reference attribute to a Companies folder. The Attribute is called “Subtasks”

In the Companies folder, I have a “Subtasks” Reference Attribute, as well as two “Subtask” Attributes. I never created a “Subtask” Attribute, and the Subtasks that I have connected to companies are distributed between the two names. The “Subtask” Attributes are duplicates of each other, and I can’t edit them.
