Using custom data configuration default
Out[2]: 
{'sentence': 'Im Falle von Umweltbelastungen kann selten eindeutig entschieden werden, ob Unbedenklichkeitswerte bereits erreicht oder überschritten sind, die die menschliche Gesundheit oder andere Wohlfahrts»güter« beeinträchtigen.',
 'is_variable': 0,
 'variable': [],

~~I have forced the refresh of the split in the preview without success.~~

I have forced the refresh of the split in the preview, and now it works.

OK, thank you @e-tornike.

I'm closing this issue as it was solved after forcing the refresh of the split in the preview.
