Logitech remote give double press

Have an issue with double press when using harmony logitech remote with Minix x8h. It's not every press but from time to time. Have latest firmware 7 installed. This issue has been around with older firmware versions also. I have tried in logitech tool to delay keypress but that did not work. Have not any issue with m1 remote.

Anyone else having this issue?
Any suggestion what can be done or is it an bug in the firmware?

Thanks in advance
Kristian
