Inactive arrow keys and obscure black dot on slide.

Hello.
I made a slide using the standard slide tool and elementor. Elementor has arrow keys and an option to add or remove points. How can I fix the direction keys that do not work on the screen, and a black dot that has shifted to the area below, even though I removed it from the setting there.
