keybind issue

Hey guys! I just opened The Sims 4 today and entered my family lot. I wanted to decorate a room, but when I pressed the '9' key to move an item up, it moved my camera to a specific point on my lot instead. I don’t know how to fix it, and it’s so annoying! I also have a clip so you can see what I mean. If anyone knows how to solve this, please help!
