I am importing a csv file using read csv node and when I run the node, all my column names in the node monitor only shows the first letter of the actual column name.
When I add a node for example Column rename, I see the names normally
When I do an unpivot node, I see the real column name with an underscore (_) between each letter
When I do an excel writer, the column has all characters separated by a ? instead of the underscore,
At first I had to click on support short data rows as there were some problematic rows. Now I unclicked the box and the column names are OK and the problematic rows from short data are magically not an issue anymore.
