Gradient Color Box Dissapearing

[MEEP of Faith]

When I change the color of one of the gradient sliders to a non-swatch color the whole box diappears, but the initial shape still gets the color change.
How do I stop this from happening?

Note: My color settings are on RGB.

This information would help us assist you accordingly. Looking forward to your response.
