Post From: Topstep Rithmic Error when scaling in a bracket order

I'm going through the Topstep Combine. When I place an order, I use a market buy/sell with a Limit and Stop bracket. I don't experience any error when I first make this trade. However, when I go to scale in an additional contract, the Trade Service Log pops up with the below error. I know this error is coming from the Rithmic side, but I'm wondering if there is something you guys may know from experience as to the cause of this error - perhaps the bracket orders I'm using need to be different for compatibility with Rithmic, or I need to somehow scale in differently. I do not experience this error when trading this bracket order through Teton.
