Error with Set Values of Multiple Element

Hello, I am currently having an error with the parameter set insertion, it doesn’t work exactly as I described in the image below, the left is my test project, the right is my real project. I’m doing, can someone tell me why not, thank you.

Can you post example files, and the Dynamo code?
I don’t get what’s the problem here exactly…

Thanks you , my problem Resolved, this error from my filter by bool mask.
