@Juun89 Yea, the problem is that you have the same name. Just change your name in one of your accounts, at least one character must to be different. Then re-add your account in kodi and you should see the new name there and your problem should be fixed.
Let me know.

To be sure I changed the names on both my accounts. They changed everywhere I log in (windows, onedrive, ms account) just not on Kodi/OneDrive Addon... Any suggestions? I even tried to re-install Kodi, to no avail.

To clarify; it still displays the old names for both accounts, even after full re-install of Kodi, addon and accounts (revoked permissions and everything).
