Shield UI grid wrong value on edit whe grouping

Question

I am testing this grid. It has several interesting features. But doing something very basic I find a problem that makes it practically unusable.

When the grid is grouped. If I try to edit any record, the value that is displayed in the editable field does not correspond to the record. Afterwards all the data in the registry is lost.

Here is a codepen

HTML:

<div id="grid"></div>

JavaScript:

   jQuery(function ($) {
        $("#grid").shieldGrid({
            dataSource: {
                data: gridData,    
                schema: {
                          fields: window.orderFields = {
                            "name": {path: "name", type: String},  
                            "company": {path: "company", type: String},  
                            "email": {path: "email", type: String}  
                          }
                        },
                group: [{ field: "company", order: "asc" }]
            },
        rowHover: false,
        sorting: {
            multiple: false
        },
        selection: {
            type: "row",
            multiple: false,
            toggle: false
        },
        grouping: {
            showGroupHeader: true,
            allowDragToGroup: true,
            message: "Arrastrar aqui para agrupar"
        },
        scrolling: true,
        columnReorder: true,
        resizing: true,
        filtering: {
            enabled: true
        },
            columns: [                
                { field: "id", width: "70px", title: "ID", editable: true, groupFooterTemplate: "Cant. : {count}" },
                { field: "name", title: "Person Name", editable: true, groupFooterTemplate: "Cant. : {count}" },

                { field: "email", title:"Email Address", width: "270px", editable: true, groupFooterTemplate: "Cant. : {count}" }
            ],
        editing: {
            enabled: true,
            event: "doubleclick",
            type: "cell"
        }          
        });
    });
