The data conversion for column "MyColumn" returned status value 2 and status text "The value could not be converted because of a potential loss of data.

I have a flatfile datasource with quite a few columns.
On one column I set the datatype to 8 byte signed integer. It worked but then i realized that a 4 byte would do, so i changed it to 4 byte and refreshed the flat file source shape.

Now i get the following error on the FlatFile source shape when i run the package:

The data conversion for column "created" returned status value 2 and status text "The value could not be converted because of a potential loss of data.

I have checked the connection, flat file connector, each pipeline and each downstream shape. all see the column as 4 byte signed int.

I have built and rebuilt the project.

I still get the error mentioned above. is this a known bug when refreshing/changing metadata or am i doing something wrong?
