Regression bug: NonMatchingSplitsSizesError for (possibly) overwritten dataset

[finiteautomata]

Describe the bug

While trying to load the dataset https://huggingface.co/datasets/pysentimiento/spanish-tweets-small, I get this error:

---------------------------------------------------------------------------

I think I had this dataset updated, might be related to #6271

It is working fine as late in 2.10.0 , but not in 2.13.0 onwards.

Steps to reproduce the bug

from datasets import load_dataset

ds = load_dataset("pysentimiento/spanish-tweets-small")

You can run it in this notebook

Expected behavior

Load the dataset without any error
