Anchor point is missing on guide line

When the mouse hoover on the path, the guide line shows without anchor points. Anchor points will only show once the path is selected.
I tried ctrl+u, ctrl+h, but none of them work. I also try to set the preference to default, but alt+shift+ctrl isn't working for some how.
I tried to re-install it, but the problem still exists. I really need help, thanks!
