Hello
I tried to replace the label with a class but as you can see in the image the value in the result is (?)
All settings are fine, but without the result I expected

Hi,
In your “label” column there is a backslash (“\”) and in the “image” column it is a forward slash (“/”). This is why it does not match. You can use a String Manipulation node with the replace() function to fix it.
Kind regards,
Alexander
