deck.gl styles certain parts of map not others

Question

I'm encountering a weird bug with my deck.gl map. The polygons all load, but some of them get colored in appropriately, while others don't. When I zoom into these uncolored areas, some more color appears, but when I zoom back out it goes away again.

Here's a chunk of my code:

  \\config stuff
  deckgl = new deck.DeckGL({
      container: "map",
      map: maplibregl,
      mapStyle: "https://basemaps.cartocdn.com/gl/positron-gl-style/style.json",
      initialViewState: {
        latitude: 38.302222210685656,
        longitude: -98.51898888084287,
        zoom: 4
      },
        controller: {dragPan: true, scrollZoom:true},
        layers: [
          new deck.carto.CartoLayer({
            id: 'polygons',
            connection: "carto_dw",
            type: deck.carto.MAP_TYPES.TABLE,
            data: "carto-dw-ac-whspeled.shared.polys",
            getFillColor: deck.carto.colorBins({
              attr: "time",
              domain: [3, 6, 9, 12, 15, 18, 21, 24, 27, 30],
              colors: [[255, 247, 236, 150], 
                        [254, 232, 200, 150], 
                        [253, 212, 158, 150], 
                        [253, 187, 132, 150], 
                        [252, 141, 89, 150], 
                        [239, 101, 72, 150], 
                        [215, 48, 31, 150], 
                        [179, 0, 0, 150], 
                        [127, 0, 0, 150], 
                        [102, 31, 31, 150], 
                        [77, 0, 0, 150]]
            }),
            getLineColor: false,
            lineWidthMaxPixels: 0,
            useDevicePixels:false
          }),
\\other layers + tooltips

Example: One city gets loaded but not the other

I've tried doing some optimization recommended by the documentation (turning off pickable and useDevicePixels). Not sure what else to try.

Is this a Web GL rendering issue? Is there anything I can change to make things better?

Thanks!
