It’s possible that fill settings of the vector are incorrect. Try to use File Rule Editor Plugin to correct it.

We’ve tried but it still doesn’t work 😕

Can you share exported vector here?

I can’t share an svg format here, but here you can find a Figma file with the icon.

I see that the fill is still using even-odd rule, which may be the problem I mentioned earlier.

Export icon from this file and tell me if the problem is still there.

I tried to export the icon from your file but the problem is still here…

Can you try again? I merged box object with books, maybe that will somehow help.

The problem is still here… But when we export the icon with Sketch the problem is corrected so we take this alternative today. I don’t know if the problem comes from the Figma export 😕

This is likely because there is not a vector fill in the icon. Without this, there is nothing to export.

See this image. I added a vector fill layer.

This exports as you wish.
