Rii i8 keyboard problem

Hi guys!
I’m new here and I have problem with hardware which is connected with Kodi. On my Rii i8 keyboard some of keys doesn’t work properly. When I click 8, 9, i, o, k, l, ., , on my system writes: 89, 89, io, io, kl, kl, ,., ,., (same order). Anyone had a same problem? It’s really annoying!
