After importing, changing the horrible Title to eliminate the email address & compiling successfully I made a manual change to a Libronix file and re-imported. It created another PB entry with the same docx files as the original.
The fact that another PB entry was created is expected behavior, since the original PB entry was renamed.
However, the fact that you got your email address in the Title (rather than your name) might be a bug. Were you working online or offline when you tested this?
I reproduced the email in Title whilst being offline in Beta 4, but got my name when importing online.
I was online at the time I reported the issue, but it is fixed now.
This is the expected behavior. When online, the program can check to find your name. When you are offline, your email should be used.
Thanks for verifying that it is behaving correctly for you!
