Hi, I have created a special column called "X-PO". I can edit it, and the new header is writtten into the mails header. Also I can search the text, but the text is not shown in the X-PO-column of the mail list. Can you please help?

I'm using Thunderbird 38.7.2

Edit: Just tested again with 52.9.0, but still the same.

This review is for a previous version of the add-on (6.1).
