Taking a look!

[leemengtw]

Same here. It only renders the first letter. Took me hours debugging and with no success solving this.

    choices=choices,

where choices are a list of strings like this:

But only the first character of each choice are rendered:

version:

gradio==3.44.0
gradio_client==0.5.0
