Typo or error in datablock and imagenette tutorial fastai docs

Hi,
I was going through the excellent tutorial in fastai docs. There seems to be a discrepancy in the text and output shown. For example, the following screenshot(Data block tutorial | fastai) is from the datablock tutorial.

the text reads, “how it changed the name “cat” to an index.” However, if you see the output above, it says TensorCategory(1), which from sorted vocab should be the dog category

Also, from the imagenette tutorial(Tutorial - Training a model on Imagenette | fastai), the screenshot is shown below.

the text reads that “how it changed the name “cat” to an index,” but there is no “cat” category in the imagenette dataset. I believe there is some typo in this part of the tutorial. Any help would be appreciated.
