Unable to access datatable column values to data bind in Custom List

Hi,
I am following the UiPath Apps training and trying to follow the example using VB expressions (which is the currently recommended approach for Apps). Since the course content is outdated I am finding it difficult to access the values of the data table bind to the Custom List.

As per the steps, I could successfully bind the data table as below.

Table to bind was given under the Process tab menu option. But when I try to bind the column values to my text boxes inside the Template, it doesn’t show the columns as shown in the video.

I tried to access the column value using ThisRow(“ColumnName”) as mentioned in the guide. But, then it says the ThisRow variable is not defined.

But now after a spending like a day clicking here and there, I tried to define a variable named ThisRow while binding the table, and then deleted that variable, and now it suggest ThisRow variable as a DataRow. Is this a bug? How did it appear all of a sudden?
