How did lists get added to my board by me but it was not me?

[Lindsay Smith]

On one of my boards, 3 LISTS appeared that according to the activity record, i added BUT I did not add the LISTS.

Hi, Lindsay.

If those lists are auto-generated when you double tap anywhere on the board in your Trello iOS app, and have animal names like "Talented Tasmanian Devil", "Comfy Koala", "Clever Cassowary", etc., then it's a known bug.

There has been a number of threads reporting it.
