BUG: Atlassian Calendar Power-up still reflects card due date in .ics output after date is removed

[Victoria]

As stated in the title, the Calendar Power-up for Trello owned/maintained by Atlassian continues to show an entry for a card at the last-used due date after that due date is removed from the card, in the power-up's .ics file output. This makes the .ics file view incorrect.

To clarify -- you mean the raw .ics file has incorrect information, and not the calendar view it's synced to (e.g. Google calendar)? The former is a bug but the latter is expected since Google cal and others poll the ics feed sporadically (every few hours I think).

If it is the former (the raw ics file is wrong), how did you create the card in question? I've noticed issues when creating cards on my board via the new inbox feature.
