Audiosuite "clip by clip" not working under 12.6

[SD2]

Hello all,

I'm experiencing a problem with AS processing when using the clip by clip option.
The process starts but, when it seems to be finished, the spinning Wheel appears and Pro Tools is "Not responding" (Finder). I have to force quit...

The processed clips seem to be in the Audio Files folder though...
It's just that the process seems unable to end properly.

Any idea what could cause this? Anyone else experiencing this?
Thanks for any lead.

I found the answer myself. There's a bug in PT12.6...
PT12.7 works with clip by clip Audiosuite processing.
