Modified Power BI custom visual and generated new pbiviz file, but not seeing changes

I'm learning about creating custom visuals, so after doing the bar chart tutorial, I downloaded the WordCloud custom visual (https://app.powerbi.com/visuals/show/WordCloud1447959067750) and modified it slightly just to see if I could see the changes reflected back but it looks the same as always. I modified capabilities.json to change the label "Data colors" to be "Data colors 2" on the formatting section that you see when you want to change the colors it uses.  Then I changed the 2500 limit to 50000.  I generated a new pbiviz file (ran "pbiviz package" in the node.js command line) and it updated the pbiviz file in the /dist folder. When I imported it into Power BI desktop and powerbi.com, it still said "Data colors" and seemed to be using the 2500 limit, although that one is harder to tell. What am I doing wrong? Is there another place to change this? I searched the whole project for "Data colors" and that's the only spot.  I had a coworker import it and he did not see the changes either. 

Change #1 in capabilities.json:

 "dataPoint": {
            "displayName": "Data colors 2",
            "properties": {
                "fill": {
                    "displayName": "Fill",
                    "type": {
                        "fill": {
                            "solid": {
                                "color": true
...

Change #2 in capabilities.json:

 "categorical": {
                "categories": {
                    "for": {
                        "in": "Category"
                    },
                    "dataReductionAlgorithm": {
                        "top": {
                            "count": 50000  //changed this from 2500
                        }
                    }
                },
                "values": {
                    "for": {
                        "in": "Values"
                    }
                }
            }
