New Lists Disappearing from Boards

[KC]

Anyone else having issues with new checklists disappearing on Trello boards?  Just started this morning.

EDIT: New LISTS disappearing from Boards, not checklists disappearing from Cards.  Apologies for the confusion!

Hi @KC 👋🏻

If you have hit the checklist Item limit of 200, then Trello lets you Add but the item disappears.

You could try the following:

• You can try deleting some old, completed items from the checklist to add new ones.
• Make sure there are no hidden items in the checklist.
• Try logging out and signing in back and re-load the board. Sometimes clearing cache also helps.

I hope this answers your question. 🙂

Thanks,

Hi @Anwesha Pan 

Thanks for the response!  I should clarify -- I think I meant just a regular "List" on a Board instead of "Checklists" within a Card.  Whenever I create a new List on a board, after about 5 seconds, the List completely disappears from the board, taking any cards I may have created within it.

I have tried reloading the page, rebooting my computer, and clearing my cache.  None seem to have worked unfortunately, and the problem persists throughout all my different Boards.  Existing Lists seem to be unaffected.  Any ideas?

Thank you!

Ah thanks for clarifying @KC 🙂

I can understand that's frustrating, may be you can give a try for the following options:

1. Look at the board activity feed and see which account took the action to archive the card (you can also see this in the card's own activity feed)

2. Check for Butler automation rules: This is the most common cause. A Butler rule on the board may be configured to automatically archive newly created lists. To check:

   • Open the board menu → select Automation (or the Butler icon)

   • Look through your rules for anything that triggers on "when a list is created" and performs an "archive" action

   • Disable or delete any such rule

3. Check for Power-Ups: A third-party Power-Up could be triggering list archival. Try temporarily disabling all Power-Ups on the board (board menu → Power-Ups → disable each one), then create a test list to see if the problem persists.
4. Clear Board Filters: Check the top right of your board for an active search filter (e.g., a green indicator saying "X search results"). Click the "X" to clear it and reveal all lists and cards

Let me know if any of these worked for you. 🙂

Thanks,

Hi @Anwesha Pan 

It looks like the issue corrected itself!  It wasn't working for about 3 hours, but now the Lists are no longer disappearing.  Might have just been a temporary back-end bug?

But I really appreciate your time and expertise in helping me with this issue!  I will definitely use your listed steps to troubleshoot in case the same issues arise in the future.

THANK YOU!  :)
