Component export issue

I have created an icon placeholder component to main the icon size consistency in my application. when I use the icon place holder component and replace it with icons inside, during export it's not exporting all icons. The assets are overriding even if they are labeled differently. I have to manually ungroup the component and then name it back to export all assets. I have attached the source file and a few screenshots. One from XD an application where it shows 6 assets as downloadable and the other screenshot is from cloud developer handoff where it shows only 3 assets.
