Resizeable Box in product variation price/files

Hello,

1-Assuming that so far after many problems the new version is working, I’d like to know why the boxes in the backend related to product page variation for download/virtual are not anymore draggable/resizeable.
It’s very hard to set File Title and Check the correct title added.
It’s a plugin problem not of the theme and before it was very useful to drag the corner and make any check.

2-Besides, I don’t understand what happen if I don’t set a title in the file title box in the virtual/download variation, does it be empty in the receipt or report the filename?

3-In the attribute if I check not to show in the front end it is still there the variation name. I mean if I have an attribute like “Size” and 3 variation, I’d like to show only the variation without the word “Size” but I cannot.

Thanks
Angelo
