Help required - issues in number formatting and aggregations

We’re facing some issues in number formatting and the aggregations on the measures while loading the PivotGrid. For your reference I have attached the sample code along with data, and it can be downloaded from the URL
Few details about the sample application to replicate the issue:-

1. It’s an angular application, and the angular component to load the pivotgrids are available under path “\src\app\pages\pivotgrid\”.
2. Internally the data is loading from the path “\src\assets\Data\”. Both the json data and the code for configuration of the Pivotgrids are loaded from the CacheJsonData.json and ConfigData.json files respectively.
3. When executing the application it doesn’t require any credentials to login.
4. In the left menu click on the “PivotGrid” option to load the pivotgrid components.
5. On changing the dropdown, the different pivotgrids with different set of data can be loaded

 
Issues:-

1. % not working correctly :

As per the documentation, if we need to have any % (percentage) column, then we need to set the following properties i.e. "formatAsPercent":"true", “isPercent":"true" in the formatter section (it is defined in \src\assets\Data\PercentageIssue\ConfigData.json).
We tried implementing it but looks like correct properties are not being assigned, and hence the % column is not working as expected. Please refer the snapshot for the issue.
  2. Sell Price column aggregation should be on average, instead it is summing up:-
Please refer the json data file \src\assets\Data\SellPriceIssue\CacheJsonData.json, which contains the actual data to load the pivot grid. As per the documentation if the aggregation has to work correctly, then the first record of the json data should have the datatype defined in it.
For the column “Sell Price”, we have defined as "Sell_Price": {      "type": "number"    },
Also in the measures in the \src\assets\Data\SellPriceIssue\ConfigData.json, we have given the aggregation as “avg”. But while loading the pivotgrid it is summing up?
 
  3. Column headers alignment:
We have a requirement in which the column headers alignment also to be defined dynamically from the config json data. Can you please clarify what is the correct way to achieve this?
