One thing I really love about the new CW shops is that it keeps up with how many of an item you sold.

However, it doesn't appear that feature is working right now :( Or, at least not for me.

I put into my CW shop today and have sold a few but the counter hasn't gone up. I have also sold a few Houndstooth copies and that still says 0 as well. Halp?

yes. Most notably to the unlimited count items that have been uploaded after the switch to the new shops.
