ccxt: Okex sandbox problem with watch_orders. newUpdates : True sometimes does not work

OS:Windows 10 Programming Language version: Python 3.9 CCXT Pro Version 0.9.90 ( just subscribed it) CCXT Version 1.71.96 Exchange Okex sandbox

okex_test = ccxtpro.okex({'verbose': True,
                                  'enableRateLimit': False,
                                  'apiKey': '',                                
                                  'secret': '1F,
                                  'password': 'P,
                                  'newUpdates': True,
'                                 'headers': {"x-simulated-trading": 1}, # https://github.com/ccxt/ccxt/pull/11108
                                 ​'options': {
                                     ​'tradesLimit': 1000,
                                     ​'OHLCVLimit': 1000,
                                     ​'ordersLimit': 1000,
                                 ​},
                                 ​})
  okex_test.set_sandbox_mode(True)
  markets = await okex_test.load_markets() 

Having instantiated the exchange like in the code above, with newUpdates': True i do order = await okex_test.watch_orders(symbol)

when I send a market order to OKX I usually get 2 responses:

1. 'type': 'market', 'status': 'open'

after few mls

2) 'type': 'market', 'status': 'closed'

sometimes I do not get the 'type': 'market', 'status': 'open' first answer but I get 2 'type': 'market', 'status': 'closed' answers one is relative to my last order and the other one to the previous order, This should not happen with 'newUpdates': True,

I cannot replicate the issue because it happens only sometimes and it would be extremely difficult to post a snippet of my code ( the okx market order is sent only after a limit order is filled on another market ).

can you please help me investigating this problem
