Looking at the sample I get the impression your export file exists of three parts. Very weird...
Anyway, if this correct you would have to pipe them in the right order since the language info is in the first part.

If however the files are seperate export files and you want to apply them all, you would import them one by one.

In any case I would leave out the pipe altogether as it does not have any advantage. The only case I can imagine where you would use this is when you have a compressed export file and don't have the space to uncompress it.
