Q&A in Activity Stream

In the options it is possible to set a hook at:

"Checking this will disable commenting for the question asked notification in Buddypress Activity Stream, forsing user to answer the question through plugin generated pages."

But the Answer ist still in the activity stream of Buddypress.

AND

The Question itself is shown in this way in the activity stream, while the Topic is missing:

" xyz asked “” "

also the answer to it:

" abc answered question “” "

How can this be repaired and when will be an update to remove this failure in the future?
