BTT and Keyboard Maestro clipboard macros

Describe the bug
Seems that BTT doesn't monitor changes of clipboard done by 3rd party apps. I have macro in Keyboard Maestro which changes underscores to slashes (_ to /). This macro is launched by keyboard shortcut maintained in BTT (Fn + /). BTT shows old clipboard content in Clipboard Manager although clipboard content is changed.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
MacBook
