Duplicate paths

I noticed some icons have duplicate SVG paths.

For example, the ionicons flag SVG is this:

<svg fill="currentColor" height="32" width="32" viewBox="0 0 512 512" style="display: inline-block; vertical-align: middle;"><g><path d="M426.4,182.5c-35.8,5.9-94.2,7.5-133-66.1c-41.6-79.1-108.8-81.5-148.1-74.3c-19.1,3.5-33.4,19.5-33.4,35v196.6

		c2-3.5,8.7-20.2,8.7-36.2C438.2,180,426.4,182.5,426.4,182.5z"></path></path><path d="M88,32H72c-4.4,0-8,3.6-8,8v432c0,4.4,3.6,8,8,8h16c4.4,0,8-3.6,8-8V40C96,35.6,92.4,32,88,32z"><path d="M88,32H72c-4.4,0-8,3.6-8,8v432c0,4.4,3.6,8,8,8h16c4.4,0,8-3.6,8-8V40C96,35.6,92.4,32,88,32z"></path></path></g></svg>

Notice the circled children paths are the same, it seems like react-icon-kits is doubling up on the paths
