When I select part of the text in a cell in Excel and hit Ctrl-C, e.g. "Hello this is a test" (only selecting the last four words), the text is not captured by the BTT clipboard manager. Instead, it has "-".
I'm using a Mac M1 Max with Monterey 12.4 and BetterTouchTool version 3.821.
Workaround: This is fixed by selecting DISABLE Microsoft Office performance optimizations in the settings, but ideally it would work either way.
