When using gaussian blur or outer glow on top of a gradient object, the gradient underneath becomes transparent.
The object in the pictures shown is applied the outer glow effect. When I place the object on top of the shape applied with gradient colors, the gradient becomes transparent as the glow appears to have disappeared.
Taylor, sorry, but there is not much can be told by looking at these screenshots only. The better way would be to share the file, the meaningful piece of it, for the team to look at the structure and the appearance stack you have there. Can you please share it here, or send it over email@example.com, if you don’t want to make it public. If you prefer email, please add the link to this report — https://illustrator.uservoice.com/forums/601447/suggestions/45259318
