[Plugin: NextGEN Gallery] Album showed twice, bugfix not working

The problem I found is that for one album tag the nggGallery::render is somehow called twice but one of the times the html is intended to stay in a html comment. But in the album-compact.php there a re two comments and the first one terminates the major comment and reveals the following duplicated html. That’s why I deleted the comments in album-compact.php but this is just a temporary fix. Why is the same html printed out twice and one of the times in a comment?
If I want now to use the extended form I should do the same 🙂

Any better idea?
