There is a background color when I swap component

Hi all! As title, there is background color behind the icon when I swap a component, how do I fix this?

I tried to replace the Placeholder icon with another icon, but somehow there is a grey background in the icon when I do that. Please help. thanks

I would guess placeholder has a fill sitting on the component itself that is being applied to another instance when you swap it?

Thanks for your reply, yes there is placeholder behind the icon. But there is no color in it.

Can’t really say without having access to the file. But if it’s not the placeholder behind it maybe when you created the component, you accidentaly applied a fill to the instance of your icon component. And that sometimes carries on even when swapping instances. Try hitting the three dots button on the component section in the sidebar and resetting all changes
