"undefined" in calendar entry

[stodec]

As one reviewer on the Mozilla Thunderbird Add-ons wrote, the reminder calendar entry looks as follows:
"undefined" is expecting replies

I have similar problem, but only in Gmail IMAP account:
New reminder: "undefined" : All recipients have replied to this email -> no subject, text is confusing.
When creating reminder from toolbar, the "+" button, then reminder text is correct.

On another IMAP server account is reminder correct.

New reminder: "undefined" : All recipients have replied to this email -> no subject, text is confusing.
I send e-mail to myself, therefore "All recipients have replied to this email ", but "undefined" in gmail is actual.

On another IMAP account, it works, I get "Test" is expecting replied as calendar entry for an e-mail with the subject "Test". If I can reproduce the behavior, I will get back to you.

So far, I have occasionally gotten some reminders with "undefined", but I could not reproduce the behavior reliably. Until I find out what causes the "undefined" subjects in the the calendar reminders, I'll use the menu - Message - Reply Manager - View all marked messages, as the author of this add-on wrote in the comments on the mozilla add-on page.
