For me it reproduces with as simple project as:

echo '[]' > compile_commands.json

After that, I add another build configuration.
Then it seems I need to close QtC and open it again.
After that, switching between configurations prevents building the one 
that _wasn't active_ at the moment
the project was opened.

Please let me know if that's sufficient for you.
If not, then I'll go and create the bug ticket.

Thanks!
