What you described is exactly what you get when Num Lock is turned off. 1, 2, 4, 6 and 8 move the camera and that's about it.
When Num Lock is turned on you are able to use 1, 2 and 3 to change the speed. Could you test in notepad if the buttons are still functional?
so I double checked and I am able to use the numbers as they are suppose to be use in regular use but it still won't let me use it for the shortcut. I notice when the num Lock is turn off the pad does nothing.
It's correct that you can turn the num pad off. Do you have any mods or CC in game that might be messing with the controls?
Could you test and rename your The Sims 4 folder in Documents\Electronic Arts? Just add a old to the end of it. When you start the game you'll get a clean game, test it, see if it has something to do with your folder. If it still doesn't work just delete the new folder and name the old one back to The Sims 4. If it does fix the issue start moving folders over one by one and testing in between to see where the problem is located.
