This part belongs to adrian95, and you currently have comment-only permission. Ask the owner to grant you edit access through the project’s sharing settings; changing modes won’t override that permission.
If the owner can’t grant access, you can fork the part into your own account, edit and publish your copy, then replace the part in your DPC board. That would not correct the original library part or other designs using it.
I forked the part into your account: Open your editable XTR106UA/2K5 copy. The pin metadata is unchanged for now; the original library part and your DPC board are untouched.
