Markup keeps displaying

I write/insert this code

[expand title="trigger" ]hidden text[/expand]
[expand title="Guidance Box - how to find things" tag="div"]Line 1 of guidance[/expand]

This code keeps displaying:
⇓ title=”trigger” ⇓ title=”Guidance Box – how to find things” tag=”div”

⇓ title=”Q: What sorts of conditions do you treat in your San Francisco acupuncture clinic?” trigclass=”highlight”

However collapse function itself works fine.
