Link not opening in grid (Modern UI)

I’m experiencing an issue in Modern UI where a link in a grid column is not opening target screen when clicking on the field.

Here is the TS:

@columnConfig({
    editorConfig: {
        linkCommand: "ViewBills"
    },
    width: 70,
})
BillID: PXFieldState<PXFieldOptions.CommitChanges>;

When I click on the BillID field, nothing happens. I also tried adding allowEdit: true, but it did not resolve the issue. 

What’s confusing is that in another screen I have a very similar configuration, and it works correctly the link opens as expected:

@columnConfig({
    editorConfig: {
        linkCommand: "ViewInvoice"
    },
    width: 90
})
InvoiceId: PXFieldState;
