Strange VuhDo behavior

[kate]

I'm running into some very odd VuhDo behavior, and hopefully it can be sorted out pretty easily:

I want to make macros for healing that can be used by VuhDo. According to everything I've read, I can just make the macro like so:

#showtooltip
/stopcasting
/cast [@vuhdo] Heal

Or, where I have @vuhdo, I can replace it with

/cast [target=vuhdo]

I have tried every permutation of target at vuhdo and it simply will not work. It tells me I don't have a target. I've put it in quotes, I've spelt it "VuhDo", "vuhdo", "Vuhdo" etc.

I have also enabled the "target" checkbox in the spells/misc area and it does not work.

Any ideas?
