2 Chrome windows open, but when opening a new link/website it opens on the main Chrome window

So it's a bit difficult to explain this but I have a 2 monitor setup, I normally have 2 Chrome windows open, 1 on each monitor.

In the past I was able to click links to open them within the same Chrome window, now when I do this, it opens it on the Chrome window on the main monitor. The most frustrating part is that it doesn't even open it as a new tab, it replaces the active tab on the main Chrome window.

This means if I'm watching a video, reading some text, etc... it is then replaced by a webpage which I wanted to open on my second monitor with the second Chrome window open.

Does anyone know why this is happening?
