Truncate (or Padding) Input

[bifterciabata]

Hi, I use ludwig version 0.10.4. I try to use for finetuning paraphrase task using indonesian dataset.
Here is my prompt (in Indonesian)

prompt:
  template: |
    Instruction: Parafrasekan kalimat yang diberikan dalam Bahasa Indonesia dengan mempertahankan makna asli tetapi menggunakan kata-kata dan struktur yang berbeda.

    Input: {input}

    Response:

But in validation I got this

My question is:
Why there is ! before instruction?
Is it because padding? and translated to ! ?

In preparation log I saw
No padding token id found. Using 0 as pad token id. Can we modify this padding token?

Thank you
