Pagination is not updated when doing approve all or reject all.

Request status is still pending in Calendar although I clicked approve all.

Not yet resolved.

[zaelgohary]

Issue is still not fixed. Request is being shown as pending while it's approved in the network tab.

Also, the notifications are messed up as the notification that should appear to the supervisor, gets shown to the user.
