Polygon "randomly" doesn't fill

Hi,
I am have a weird bug - Frequently, when adding polygons in my 2D map, the polygons don’t have any fill color, and the shape doesn’t “close”.


The same behavior happens with ellipses and polylines as well.
I will also note that when a polygon doesn’t load well, so does any other polygon/ellipse/polyline until I restart the browser (sometimes multiple times).

The behavior sometimes happens and sometimes doesn’t even when I load the exact same shapes.

Any help would be appreciated, thank you!
