window filter - sometimes "enter" not establishe connection

When i open filter window and find connection I press "enter", the window disappears but does not establish a connection.

Sometimes need restart RDM and key "enter" working. I don't have checked option from attachment.

Coud you help me to resolve this problem, it is very annoying if you must use two-click from mouse to establish connection, when you try to use only keyboard shortcuts when working with ssh terminals.
