The attribute delete SOP is not working in the latest build 2023.11510. it tosses up a warning which might be fine, but it also didn’t actually delete the attribute. This was working fine in previous builds. I’m guessing it is related to the new sequence parameters that have been added to the node, because of what the warning message looks like. Simple test case attached.
