I can only think you are not using the tool correctly, I use it daily with no issues, regarding opening a new trade with the same stop loss, this is not possible with the Risk & Reward tool as it only allows a single buy or sell per symbol unless you use a unique ID.
This may help.

Are you sure you are not talking about the risk and reward displayed stop loss and take profit targets and not the actual position stop loss?
Share a screenshot explaining what you are talking about and also a step by step description of what you are doing.
