Hi @Ioana,

I have sent you a workflow in a privat message on same day you asked for it.
Did you receive it? When can I expect an answer?

Thanks for your help.
Kind Regards,

For other ppl running into this:

  • we are fixing a small issue, but in the meanwhile,
  • make sure you are configuring ML extractor correctly (with the right fields and columns, by using the Get Capabilities feature whenever possible)
  • make sure you are configuring your Regex extractor correctly (an explosion of overimposing values will lead to too much highlight in the UI and will render the text unreadable).
  • we will look into fixing the display issue as well.
