I assume that this is a league(s) that you have re-created year upon year. You might have to ask the SC admins to alter your legacy leagues to enable 20 as an option. Alternatively, you might have to delete the league and start anew, which should enable league size to be set from 6 up to 20 next season.
Maybe try changing starting round to round 2 first, then try changing the number to 20?
I did it with a League I've been running for the last 5 years or so, from 18 to 20.
That happened once to my Mate in the NRL SC League.... he had to email them directly ( under Contact, I think ) and they did fix it somehow... hope that works for You too... fingers crossed
