The CW can be a powerful tool but it also has some oddness in editing. I have advised GS of some of these. It is a tool you need to "learn" and given some of the things that can be asked of it, it can be quite robust once mastered even though sometimes results can be unforeseen due to conflicts between "Scheme" and in place editing.
To answer you question: Yes it can be problematic.
Tip: If you are working with "Schemes" it can sometimes be easier just to retain the settings (use Alt-Clk if the values aren't current in the CW tool) and redraw the curtain wall.
