Hi,
The used password was the correct one, I done a copy/paste of it, but no luck.
So if you change the ordering of the actions it still doesn't work ? And what about having only one action, only the export one ? Does that work as expected ?
Regarding the products next to each other in one row in the export, this is not an issue, this is the way it is working and was working before 
This can be changed thanks to custom code, the best solution would be to create a mass action plugin, add another export action and use the current code for the export and adapt it to your needs. This require PHP knowledges.
