Multiple Grids expanding when only one button clicked

[WynApse]

I'm jumping in on a project that has 3 grids one below the other each in their own div.

Each has collapse set true as shown in the documentation.

If I click the top one to expand -- all 3 expand!

Any thoughts on either why this happens or how I can stop it?

Could you please share a jsfiddle so that I can look into it.
