Import example pre annotation data do not import label

**Describe the bug**
I tried to import your example on https://labelstud.io/guide/predictions.html json file. Image is imported but not the label text as label. I did it step by step and of course I made sure beforehand that the label is created in the annotation as Label "Text". After import image and the box is displayed to me with the text, but not with the label "text", only the default label orange

**Expected behavior**
I would expect that the label set in the json is also automatically mapped via import with the label created in the setting/annotation.

**Environment (please complete the following information):**
- Windows
- v1.12.1
