What tool textures are you using? (a screenshot of just the tool brushes would help a lot). A brush normally must be entirely covered in a tool texture for it to work properly. i.e.: an areaportal has to have all 6 sides in the tools/areaportal texture or ense it will be wonky.
Also I heard somewhere that certain tool textures don't work in TF2 and you might be using those. You'd have to ask someone else for specifics, though, because I can't remember which ones.
Other than that, I don't know what could be causing the problem.
