I set two touch bar
(1) Copy: send key CMD-C
(2) Paste: send key CMD-V
In most time, the touch bar is OK.
Sometimes missing the CMD key.
When I touch the "Copy" button, only "C" was sent.
When I touch the "Paste" button, only "V" was sent.
This bug seems only occur in Parallels Desktop.
But most time, it is also OK in Parallels Desktop.
In other application, I do not find problem.
How can I modify the setting?
Or wait for newer version of BTT to fix the bug?
After seeing the reply for similar condition, I think about the cause of problem.
I try to use Ctrl-C instead of Cmd-C, and Ctrl-V instead of Cmd-V in Parallels Desktop.
It seems OK.
I will need to try again in future days to confirm it will be always OK.
