Yes, I have this issue as well in the new invoicing, you cannot insert a line.  You can't add blank lines and then choose a service.  I don't see any way to add a line?  You are asking us to rearrange them, which I can do, but how do we get a blank line?

Also, when you are invoicing off "time charges" and select "add all" they are entered backwards, with the newest at the top.  

There are a LOT of bugs with the new invoicing, hopefully QB can sort them out soon.
