Error importing CSV – Really Simple CSV Importer Debugger add-on installed

Hello,
first of all pardon my english but i have a problem importing data with your plugin Really Simple CSV importer.
I already search old topics and i found your link to your Really Simple CSV Importer Debugger add on.
I can’t find a problem with the csv structure, it seems all fine but it doesn’t update.

This is an example record from the output debug.

1.$is_update:

bool(false)

$post:

array(4) {
  ["post_type"]=>
  string(8) "listings"

Can you help me understand what’s wrong?
Thank you in advance, meanwhile i keep banging my head and try something with the output

Kind Regards
P.s Just for you to know, i have 950 records and almost 50% were updated without trouble. The other 50% have an error log like the example code above and looking at the array structure it does not seem wrong..
