Steps to reproduce

in knowledge base when setting chunk settings

  1. choose parent-child chunk mode
  2. choose paragraph mode
  3. set delimiter for parent and child

incorrect result:

Image

  • the single line below my delimiter "%%%" becomes a paragraph instead of entire section, and even though my delimiter is not present in next line

✔️ Expected Behavior

i expect everything in my delimiter "%%%" to be in a single paragraph, and child chunk also separate by its own delimeter "###"

   `eg : 
    %%%
    ## url: <my url>
    ## 2 Getting Started SQL Account System
    ### 2.1 How to set Financial Period & System Conversion Date[​](#21-how-to-set-financial-period--system-conversion-date "Direct link to 2.1 How to set Financial Period & System Conversion Date")
    
    1.  **Tools | Options**
        
        ![2](]<image url>)
        
    2.  Select **General Ledger**
        
    3.  Select **Financial Start Period & System Conversion Date**
        
        ![3](]<image url>)
        
    %%%`
  • the entire section should be 1 single paragraph with child chunks

❌ Actual Behavior

got multiple parent chunks instead:

parent chunk 1 :  ## url: <my url>

parent chunk 2:  ## 2 Getting Started SQL Account System

parent chunk 3:  ### 2.1 How to set Financial Period & System Conversion Date[​](#21-how-to-set-financial-period--system-conversion-date "Direct link to 2.1 How to set Financial Period & System Conversion Date")

1.  **Tools | Options**
    
    ![2(]<image url>)
    
2.  Select **General Ledger**
    
3.  Select **Financial Start Period & System Conversion Date**
    
    ![3](]<image url>)
