rel highlander not working

Hi, I’m having an issue were rel highlander tags doesn’t work. I have 5 separated text blocks with: [expand title=”Trigger Button” rel=”inforow-highlander” /]

Each text block module have id: singlerow and class: collapseomatic

Each Trigger Button open an inner row, each followed by the other, with text blocks: [expand rel=”inforow-highlander”]Bloque 1 I am text block. Click edit button to change this text. Lorem ipsum dolor sit amet, consectetur…./]

Each inner row have id: target-singlerow1, 2, 3, etc and class: collapseomatic_content

The issue I’m having is that the trigger buttons are not hiding the rows that are not assigned to their id. I even tried with the example in the documentation:

[expand title=”Monkeys” rel=”animal-highlander”]Target Content[/expand]
[expand title=”Donkeys” rel=”animal-highlander”]Target Content[/expand]

But is doing the same, not hiding Monkeys or Donkeys when the other is triggered.
