Three cosmetic issues

Hi,

Just used Hikashop for the first time this week, and I definitely like it a lot better than other e-commerce systems I've tried. I have uncovered two cosmetic issues that I'm hoping would be easy fixes.

On the checkout page if you remove a billing address you get a language key that is not properly matched in the English version. (See attachment)

On a category page, I wanted to turn on page heading as well as set the browser title. I did this in the menu item for the shop. However it still keeps showing "product category" instead of the title I set.

Finally, on that same category view, the title text for both categories is the name of the second category. Likely a loop issue? (See attachment for this and the previous item.

Ok. I figured out that I can fix the "product categories" issue by changing the name of the root product category to be the name of my shop.
