Weird Order Placement with Paper Trading Futures

Hello all,

I have been experiencing an odd situation with trying to paper trade futures yesterday and this morning.

Yesterday I was papertrading MES and a number of times The system entered into positions that I did not feel like I told it to make. I am wondering if this is somehow related to using bracket orders and maybe the unfilled order was not being properly canceled when my SL or TP was hit.

Is this a common occurrence that others are aware of?

It's not been a huge problem while actively trading as I was able to manage the trades I didn't mean to enter to break even or slight profit, but today I opened the app and had 3 contracts and was down a total of $150. I'm not overly worried as its just simulation but I would like to understand how this is happening as I want to make sure to avoid any situations like this when trading live.
