If you add a profile to the collection, the collection number won't be refreshed when changing the target category. You have to disable and enable the colleciton number in order to get the correct, lowest available value.

The € currency symbol doesn't show, instead an Ä (German iOS) is displayed.

Also, child profiles aren't downloaded at all...

It doesn't even download them on the server, once you've synced either. No doubt it would should something need refreshing on the server, but that might not happen for a while.
