I am not sure if this is quite the right section of the forum for this, since I don't see a category for the Marketplace, but I thought you should all know about this. Please go register your thoughts with LL. Possibly file support tickets as well. I have noticed this setting stays stuck in the checked condition as well, which makes it impossible to even see the KittyCats listed on the MP now.
I'm not sure the details are entirely clear yet but it appears from conversation on this particular thread that LL did this on purpose. If anyone gathers more info please add to this thread. But meanwhile, let them know this is not okay (there are at least five separate threads about this at this new feedback site but this is by far the busiest one):
