Greetings once more, Reika!
Thank you for your patience with waiting for a response to your report. After thoroughly investigating your matter, the development team determined that no issue could be found with the command. According to their investigation, it looks like the problem is with the macro due to them having 2 commands which require a selection of a sub-target. Try removing one of the heals out of the command, like /ac "Cure II" . I hope this helps you with your commands, and I wish you the best of luck!
