Unable to refresh grid

[b17u53r]

I have a function that runs some queries on a database and returns the data on a grid.
When I try to run a different query that includes a different set of columns, then the grid does not refresh. I am unable to refresh the grid without manually refreshing the page.

This does not happen on the UDChart component.

Here is an example of the function:

Get-Report -Date "Last Year" -ReportType "Report 1" returns -> Cat | Number

Cat	Number
Cat	549

Get-Report -Date "Last Year" -ReportType "Report 2" Should return -> Cat2 | Number

On the grid:

Cat	Number
	5436

The Grid refreshes only the data that had previously populated. If I refresh the page then data is displayed correctly.

To Reproduce

Run a function that returns a pscustomobject with two or more properties and send them to a grid. Then run the function again but this time the function should return a pscustomobject with different properties.

Expected behavior

The grid should refresh automatically.
