Total number of users who have solved sereja and shuffling

In the main page of august challenge then number if users who have solved sereja n shuffling is shown as around 600 but in question’s page there are roughly around 50 submissions only.
Whats the actual amount of users who have solved it?

Basically , this is a bug in long contest page.

“Successful Submission” denotes the number of submissions which are accepted, not the number of users whose solutions are accepted.
Indeed, for PUSHFLOW, now only 15 user solved it, but we have 22 accepted codes.
For example, rns4 and mateusz95 submitted 3 codes which are accepted.
