my ZSC key isn't good, i can't change it, saying i'm not zoho expense admin *we don't use expense!!!

So how can i change it back to a good one? i tried with the super admin account and it says the same message : 

the integration can't be configured, the user isn't administrator  in "my company" or in those services " zoho expense".

Can you help me please?
