Emails not being moved to a folder in Gmail

Please take a look at following video where I am trying to move some emails from Inbox in Gmail to another folder called ClixSense, but its not moving no matter what I do:

Prior to moving, I did a search for ClixSense emails in Gmail using the search text box in top right corner of em client.

I am trying out the Pro version before buying it. The emails never get moved  and I feel there is some problem with your app.
