What version are you working in? Sounds like you're bumping up against the C/C++ beautifier trying to beautify your alias expansion. To get to the C++ beautifier settings, in the Tools > Options page, under the C/C++ language setting, go to the Formatting section. From there you can pick the beautifier profile and click "Edit". Search for 'case' in the beautifier settings, and under "Indent Rule Exceptions" you'll see the "Indent" and "Brace aligned with case" settings for the case keyword. I've attached a screenshot of that dialog section. As you make modifications to the settings the code example in the left side of the dialog will update, so you can experiment.
