It looks right, there is a lot of info off-screen that will help. At the bottom of the deauth xterm screen you see the stats with the ACKs showing 6|38. That means you have kicked them and they got back on. If you reduce the font (use the volume rocker) you will see these at each attempt to kick them and the successful ones will have some numbers other than zero. Deauth is not supposed to disconnect them completely, just force them to auto re-negotiate the connection, which is what the deauth attack relies on for collecting handshakes. The client may not appear disconnected, but would not be able to transfer any useful data over the link, because it is busy re-negotiating the link.

"BSSID" is the AP and "Station" is the client.

To check whether you have a handshake, run the decrypt function with a dictionary, the xterm screen that opens will say whether there is a handshake in the data.
