My mouse and keyboard dont work right. I only can use some keys

Hello good morning.

I have a problem with my system.

I use an Raspberry Pi 3 Model B.

My Volumio Version is: 2.834

I want use a remote on my Volumio Player. I buy this one

But i have a problem. Some of working keys are Voume Up and Volume down, and the remote feature called “Air Mouse” but many other keys dont work. For example the “Back Button” to come back to the homescreen to select another source. Or the keys from the integrated keyboard from the remote.

What i can do, to fix the problem.

My english isnt the best, i hope you know what i mean thanks!
