To start off, having too many ideas is better than having too little! However, I know it can be frustrating to juggle too many concepts, especially if others are not grasping it. With that being said, many of my favorite stories or series cannot be easily or concisely explained because they are complex, which is not necessarily a bad thing! That can make your novel unique and intriguing to readers who have to get all the way to the end to fully unravel your story’s meaning.
As far as technique, it is great that you are using a plot outline template to map out what you have. I would start by highlighting what is essential to your plot. Find out if there are any elements that can be fused together to simplify what is there. Finally, consider allowing a complex plot to continue but allow more time (or more books in a series?) to work everything out. Multiple layers of mystery before full resolution is achieved keeps readers interested as long as there is consistent progress throughout a longer plot.
All in all, it may be helpful for you to have a conversation with an author for them to identify what is working and what isn’t in your plot. As a published author myself, I’m always available, and wish you the best of luck regardless!
