BUG: problems with product edit and item list on order page

Hi, since I updated woocommerce this weekend I’ve had noticed two things.

1- I am not able to properly edit existing items. Fields are missing and I can’t click the tabs to go through product characteristics fields.

2.1- On order page, I can’t see the “list of itens” anymore. It was very helpful since our orders has lots of items.
2.2- On the “screen options” tab (usually in the top right corner), I am not able to click it anymore on “order page”. It just will not show anything, it’s like a stuck tab.

Thanks!
