Cannot restore Knox backup.

I had uninstalled my knox app. I have a lot of data in it and want to restore it. I followed all the steps mentioned in this thread https://www.samsungknox.com/en/faq/w...side-container

but I'm not able to restore my data. I have kept the zip file in the said default location.But I just can't find the restore data button.

I have a samsung N9005.
