Import tab-separated text preview different to actual

Hi,

If I import tab-separated text eg:

A drop of ink may make a million think.	Anonymous
A drunk mans' words are a sober mans' thoughts.	Anonymous
A face without freckles is like a sky without stars.	Anonymous

If I click preview, it looks great, all quotes have -Anonymous as author (see attached Screentshot-1.png).

However, when I save, I seem to get only one in three with -Anonymous as author (see attached Screentshot-2.png).

If I repeat with the exact same quotes the 3rd quote may have -Anonymous and none of the others and if I repeat it again with the same text the 1st quote may have -Anonymous and non of the others. That is, it seems to randomly apply which quote gets an author.

Many thanks.
