Some plugins might be overriding this. I know two of my plugins sadly override this (I think ST2 either added Ctrl+Shift+B after my plugin, or I overlooked it). My two plugins are BracketHighlighter and HexViewer. If you use either one, they are probably causing you issues.
With that said, as soon as I release the new version of BracketHighlighter and HexViewer, I will be removing this shortcuts by default and require users to define them themselves so I do not run into this issue again. If you haven't installed either of these plugins, then it may be some other plugin by a different person.
If you currently use either of the listed plugins, I would advise you remap or remove the shortcuts in the plugins, or remap the build and run shortcut to another key until I get this resolved.
