Yes, there is a space. I studied manuals very carefully and I couldn't be mistaken in this simple example . I also didn't miss any '¬' there where it is necessary. Now to me laziness to check all this by the 101st time to tell - doesn't work. How it can be: almost all examples work except the mentioned? I will try further ...

Sorry, my comment may have been unclear - there should NOT be any spaces between the minus and the one, e.g. "-1" is correct, "- 1" is NOT correct. If you change that, it will probably work. The extra space is entered when you type the minus char and then the 1. Instead, if you type 1 then [+/-], it will be entered properly.
