OCR error, when reading ‘clues’, leading to replacement with “out-standings” (4)

I believe the answer is:

dues

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for dues that I've seen before include "Payments made for upkeep of church" , "Subscription to a club or society" , "subs" , "Membership fees" .)

I've seen this clue in The Hindu.
