Hi,

I’m using version 5.4.2, and the same issue occurred again. It’s quite strange. My guess is that it might be related to a faulty indexing algorithm. It seems to start assigning node indices from 0 — with the table creator as the first node — and continues incrementally from there. When we reset the node, it appears to start over again from 0. Just a thought :slightly_smiling_face:.

An initial scan might be missing. Once one unchecks and checks the option to standardise names it might work.

@mlauber71 :beers: Yes, you are right, this way can work. Or when I use this node I don’t configure it(This is also the way I often use it.).

Usually, after this node It may be necessary to change some names. And this may be the place where it is easy to make mistakes.

This is a bug(maybe it’s brought by the modern UI.), but it should be easy to fix.
