Crashes on importing staff emails

[Marshall_IT]

Hi,

 

I have successfully imported student emails to their work email field.

 

Using a similar csv exported from ad I am trying to import staff emails.

 

Every time it crashes on the third or fourth one, on the section you can validate your data on.

 

I'm on version 1.7.23.0

 

Thanks for a great product. So helpful!
