Back and Menu Button Not Working Since Upgrade

Hopefully this is the correct place to post (if not please move it to correct place).
I have an Android box (MyGica ATV 1800e). Since the Upgrade of Kodi to version 17 I am unable to use the back button and menu button from the remote.
Those buttons work fine when using the android box itself so remote is not the issue here.
The skin I am using is Confluence.

Please advise on how to fix this issue?

Thanking You:
