Soulstone/Healthstone ranks with parentheses (Lesser, Minor) do not work

[ESanbornSWE]

#showtooltip
/cast [nomod]Create Felstone; [mod:shift] Create Firestone; [mod:alt] Create Healthstone; [mod:ctrl] Create Soulstone (Lesser);

Creating a macro to free up space on my bars and ran into this issue. Create Healthstone works fine, but if I change it to Create Healthstone (Lesser) then it won't execute. The tooltip information shows up correctly, but no spell is cast when clicking the macro
