Bookmark instead of Remixes....

Logged-in in Safari, after searching for a new work, the opening for that piece is on the Musicians tab. When clicking the Remixes tab, nothing happens it seems but then I notice Bookmarks now has a red "1" instead. Clicking on the Remixes tab won't work until clicking again on the Musicians tab and then back again on Remixes.
I checked FireFox browser and it works normally.
