Messed-up DataFrame/HTML outputs from gradio pandas.DataFrame/HTML

I have had a project (radiobee aligner - a Hugging Face Space by mikeee) running for a while – everything has been fine until recently. Now some outputs from pandas.DataFrame and styled DataFrame converted to HTML are messed up. (To testrun: Select the first entry in Exmaples and click Submit. It will take 2-3 secs to generate the outputs: the first column of a DatFrame is missing. HTML lines way too long. Normal outputs are two nice tables.)

The project runs fine on my local Ubuntu 20 (which also uses Python3.8 as HF Spaces).

Any hints to fix the problem will be much appreciated.
