How do I prevent Unity Hub from opening projects in the newest version?

I'm using Unity Hub 2.4.3 and I need the the ability to work in different versions of Unity. The problem is that even when I select the version I want to open my project in, Unity Hub still launches the newest version. I've checked the ProjectVersion.txt for each project and it matches the version of the editor I want to launch it in. I've also gone as far as uninstalling Unity Hub and every version of the editor I had, and reinstalling just incase there was some weird mistake I made. Is there some default editor setting I'm missing somewhere?
