imap in LN // redesign template

[Database Administrator]

I successfuly configured LN for my IMAP account on gmail.

but in inbox folder in first column "from" I have name and e-mail,
like this:

Anna Kowalska

I would like to see only Name, so I tried to change column value in
imapcl5.ntf (IMAP template)

first column was field -- > From
I changed to formula -- > @Left(From; " <");

but after refresh template I have only question marks in first column.

anybody can help?

Thanks.
