Can't skip Upgrade to pro access this lesson(Skip to next not working)

[agod_22]

When we try to click on practice problems in the module Rise from 3* to 4* it opens a popup which says Upgrade to pro to access this lesson, there are 2 buttons or action link down there -

1. Upgrade to pro (this one is working fine)
2. Skip to Next (this one is not working, after clicking on this it redirect to this popup again)
