Problem with "add region"

as you can see in the screenshot, I have 3 lists of curves, if I use them separately, it works. But when I combine as tree with 3 branches, it does not. Is this a bug ?

It’s just one view or multiple views.

Try to match the the tress structure of all the inputs.

yes that is only 1 view. and also you can see the trees are match: i have 3 branches (for curves as regions each branch), and 3 branches for 3 types.

What is the error ?

You might be using the type which is not supported .

I dont see any issue.

i fount the problem, the borders can not touch each other !? so i offset to a very small distance and it runs well.

can i have another question? i dont know how the “release element” component works, i have to release one by one

Can you show me the error ?

I really can not understand what happened but yesterday, it didnot work as the screenshot but now it works. The same file. Nothing changed. Weird, but it works and that s all I need!
