JomComment - n/a ?

I activated JomComment (latest release) for Crosswords. If somebody is writing a comment to an existing crossword in the activity stream of Jomsocial it is only displayed "schrieb einen Kommentar zum Thema n/a" (somebody wrote a comment to the topic n/a). Normally I would expect that the name of the crossword should be visible.

Maverick, could you please help me again? Thanks a lot!
