Possible Change in disclosed_quantity Handling on Zerodha

Today, I noticed a change in how disclosed_quantity is updated after an order is partially filled on Zerodha.

Earlier behavior:

• Once an order was partially filled, the disclosed quantity was updated to the pending quantity.
  
• I could then modify the order without issues.
  
• In my Java client, I normally pass quantity and price in the modify call — but quantity always remained the original order quantity, and only price was actually changed.
  
• This workflow was fine until last week.
  

Current behavior (issue observed today):

When I try to modify the order (changing only price), I get this error:

java.lang.Exception: Modify Order:: Disclosed quantity should be greater than 10% of total order quantity for NSE.

Order id 250811500019571

Noticed changes:

• disclosed_quantity is now getting updated with seemingly random values after partial fills. (screen shot attached)
  
• Even though I’m not changing the quantity (only price), the modify call fails with the above error.
  
• 
  

Questions:

1. Has there been any change in how Zerodha handles disclosed_quantity for partially filled orders?
   
2. 
   
3. How can this be fixed to restore the earlier functionality?
