Cannot import multiple nodes in feeds module using csv files
You file shows 20 rows. From your description, I bet that the GUID has been the same for each import, and you have actually created one node 20 times. (Created once then updated 19 times.) You need to define a unique field in each record, with a corresponding unique field in your node (eg guid). Then feeds will map that field to determine which nodes to create (no nodes with matching unique field) or to update (node has a matching field).

Try using the Title field as unique instead of guid.
