macbook – Keyboard late when connected via bluetooth

The problem comes from my MacBook Pro (2016, 2 ports Thunderbolt 3). I've connected two adapters (HDMI, Ethernet, 3x USB) to the Thunderbolt ports. My Mac is a kind of docking station and I only use external monitors. I started using the Mac Logitech K750 Wireless Keyboard, Logitech Unifying USB Receiver connected to one of the adapters. I have noticed that sometimes the written text appears with a long delay and that it is a little unpredictable, sometimes it works well, sometimes it works horribly and so much behind … The distance between the unifying receiver and the keyboard is about 10 centimeters.

The USB keyboard works very well, there is no delay / delay. I have the same keyboard K750 but version to Windows (on Windows it works perfectly), but on Mac same situation, so late.

I've recently started using the Mac and I do not know why at all. Does any one have a similar problem and solve it? Tell me how I can get rid of this.
