Pandora D-022 remote for Pandora DX-91 LoRa, DX-90 Lora and Pandect X-3190

I have already contacted the support in russia at this address but they have not given me explanations I kindly ask you to help me thanks

I bought the Pandora Dx 91 LoRa with the D-022 remote control included, I updated the firmware and the problem is that there is no English language in the menu but only in Russian how can I install the English language? then I bought a second remote control the d 024 and I can't find any update, how can I fix it? thank you
