P: "Print to file" in Print Module fails to export

I am running OSX El Capitan and 50% of the time Print to File fails to export the file. Have to try a second attempt which is always successfull.
I don't get any error message (also export progress bar is ok), it just does not save the file in the chosen location.

I can also predict when it fails and when not, the "Save as" window in the Finder is slightly different.

Am I the only one with this issue?
