Post From: Attached Order question/problem

Yesterday a strange behaviour occured in a live trade (broker = IB).
Before I get to this, please let me verify if my understanding and settings for what I want to do is correct:

I use a simple bracket (=attached) order.
- parent order (entry) and two child orders (stop and target)
- "Support Scale-out" is checked

With this "configuration" I somtimes decide, while being in the trade, to change the size of the target to 50% of the position.
Example:
- Simple bracket order EUR/USD Long 100K
- I change the target to 50% (50K) and after a while this target gets filled
- The stop size automatically changes to 50k as this is the ramaining position
- Now there is no target in place for the remaining (50K) position, so I manually put a limit sell in the DOM and change the size to 50K.
Because "Support Scale-out" is checked "only" this limit sell is put in the DOM/send to the broker and it gets an OCO with the existing stop order. So, when either the "new" target or the stop gets filled, the position will be flat and the open order on the other side will be canceled. Is this correct?

This is what I want and according to several tests in SIM mode with this "configuration" is does as described above.

Yesterday, in live mode, it acted different though. At the moment the 50% target got filled, the stop order was cancled/deleted automatically leaving me with an unprotected 50% of the initial position. I then manually added a stop and target for the remaining position.
How can this behaviour be explained? Am I doing something wrong here? Strangely it's working in SIM mode?!

I've attached the twconfig-file and the TradeActivity log from the live trade.
