I have three of these keyboards. They all suffer from very bad key-bounce on the mouse buttons.
What is Key-Bounce?
In the world of electronics and computing, key-bounce (often called chatter) is a phenomenon where a single press of a button or keyboard key is registered by the device as multiple, rapid presses. While it feels instant to your finger, the mechanical action inside the switch is actually a chaotic, microscopic event.

Software solution
There is a simple software only solution if you are running Linux. Linux uses libinput to control human input devices. There is a folder /etc/libinput. If this folder does not exist you can create it. You must be root to create the folder because the etc folder is owned by root. You would use the sudo command as follows:
sudo mkdir /etc/libinput
You then need to edit a file in this folder named local-overrides.quirks. Again you must be root.
sudo nano local-overrides.quirks
You need to add the following lines.
[Logitech K400 Plus Mouse Bounce Fix]MatchName=Logitech K400 PlusModelBouncingKeys=1
Save the file then reboot. This solved the problem for me on all my computers.
