A question about tokenized_text

[Hyeonah]

Hi Grace,
I'm sorry that I kept asking questions but I don't think the first token can be fixed with my codes.
{
"type": "tokenized_text",
"content": "The Bûche de Noël cake, is, a, French, Christmas tradition",
"self_paced": true,
"delimiter": ",",
"key_advance_instruction": false,
"mode": "plain"
}
These are the codes that I wrote, but the first token "The Bûche de Noël cake" only appears after I press the space bar.
Could you let me know how to fix the code? Thank you!!
