Dataset Viewer issue: DatasetGenerationError

The same issue shows up in two places. Loading the dataset fails with the same error that viewing the dataset gives.
Issue 1. - Load_dataset fails
I get the following error when I try to load_dataset with:
fleursR = load_dataset("google/fleurs-r", cache_dir="fleurs-r_dataset")
Generating train split: 0 examples [00:00, ? examples/s]Failed to read file '/root/.cache/huggingface/hub/datasets--google--fleurs-r/snapshots/c621c0b7b569dcebcd50273a187a35d1a1fc895f/data/am_et/train.tsv' with error <class 'pandas.errors.ParserError'>: Error tokenizing data. C error: EOF inside string starting at row 1917

pandas.errors.ParserError: Error tokenizing data. C error: EOF inside string starting at row 1917
Inside that file data/am_et/train.tsv, there is no obviously bad sample. When I delete samples just trying to get the load_dataset function to run through, I get different errors about pandas columns not lining up.
Issue 2.
same issue shows up on hf dataset viewer when you follow this link...The full dataset viewer is not available (click to read why). Only showing a preview of the rows.
The dataset viewer is not working.

The above exception was the direct cause of the following exception:

This can be fixed by setting quoting=3 as infleursR = load_dataset("google/fleurs-r", quoting=3, cache_dir="fleurs-r_dataset"),
but that leads to a new error:

This happened while the csv dataset builder was generating data using
hf://datasets/google/fleurs-r/data/am_et/train.tsv (at revision c621c0b7b569dcebcd50273a187a35d1a1fc895f)
Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)

The solution: Use Git Clone.
>> sudo apt install git-lfs
>> git lfs install
>> git clone https://huggingface.co/datasets/google/fleurs-r
Do you happen to have a modified version of the dataset that can be loaded without these issues ? What would be needed to fix the data files ?
