Unable to find Details Panel in Blueprint

So my details panel is no longer showing in one of my blueprints.

Under the windows option, it is still active, and in my tabs down below, I can see it as a separate window, however I am unable to get to it. I’ve tried closing it, then re-activating it in the windows tab, but it is still appearing as a separate window… Does anyone know how to solve this problem?

Thanks.

Open up the window that it is in and drag it’s tab, so left mouse click and hold to drag and place it where you want, the editor should start showing you panes you can place it in
