Archimesh making problems when right click selecting

I’m using a scene set to metric values (cm) for some environment design. I’m blocking out the scene, and I decide to add a door from archimesh. Now, it takes multiple clicks to right click select anything in object mode in the scene, and the small text saying what I’ve selected in the bottom left corner of the screen is now green, not white. Does anyone know how to fix this? It’s becoming tedious and frustrating.
