KORE & Amazon Fire TV

I’ve noticed that the down arrow to access the FFWD/RWND, audio controls, what have you will not work with KORE, with KODI installed on Fire TV.
Although it does work with the down button on the Fire TV remote; so I assume this is a function the Fire TV is not passing thru to KODI from KORE?
Just wanted to see if anyone else has seen this issue.

Thanks…
