How do I fix Google Chrome's large icon in its Windows 10 Start Menu tile?

When I pin Google Chrome to the Start Menu, the browser's icon is unusually large. This is the first time I pied Chrome to the Start Menu after a few months and it wasn't like this before. It used to be like the other apps pied in the menu.

Here's a screenshot:

The Google Chrome tile (second column of tiles, third row) seems to be occupying the whole tile space. It's also the same with resizing the tile from medium to small.

How do I fix this? Thank you.
