Dashboard list widget icon sizes no longer match those in webmap

[Starc_Industries]

All of a sudden, the icons with my list widget have increased significantly in size and they no longer match the defined sizes of the corresponding icons in my embedded webmap (see before and after images below). I suspect that when I overwrote/updated the layer on which the list is based (i.e., ArcGIS Pro sharing to ArcGIS Online), it may have broke something (?). Is there a way to get the icon sizes in the list widget to match those in the webmap again? There are no issues with the icon sizes in the webmap -- they match those in my ArcGIS Pro source layer.
