Post From: Simulated trades randomly cancel without my action

I just opened a trade on NVDA. Six seconds later, the trade canceled.

The trade activity log says:

Activity Type: Orders
Order Action Source: Canceling order due to sibling fill
Order Type: Limit
Buy/Sell: Sell
Price: 177.31 (I entered long at 177.16 with a 10 cent stoploss, 10 cent target both being OCO orders. This does not make sense. When I activate Trade -> Show Order Fills, I can see the simulated trade actually canceled one tick above my entry point. So it was canceled at 177.17, which does not add up with this 177.31)
Order Status: Pending Cancel
Time In Force : Good till Canceled

Then on a second line, at the same second:

Activity Type: Orders
Order Action Source: Simulated order canceled
Order Type: Limit
Buy/Sell: Sell
Price: 177.31 (like before, I have set nothing at 177.31. My take profit would be at 177.26. Price did not have time to move)
Order Status: Canceled
Time In Force : Good till Canceled

The same principle applied to previous trades that canceled : "canceling order due to sibling filled" is written.
When a simulated trade is taken without OCO take profit (limit) and stoploss (stop) orders, it never cancels.
