Case Sensitivity

Are labels no longer case sensitive? I have created a query based on the label "MLP", but cards with the label "mlp" are being surfaced.

Previously, if the label was not spelled and capitalized identically, it would not surface in a query.

Hi @Sarah Krawiec, I just tried it in both Jira Server 7.9.2 and Jira Cloud and indeed, the queries:

  • labels = "mlp"
  • labels = "Mlp"
  • labels = "MLP"

ALL return an issue where the label is "MLP."

So, what you're seeing is confirmed.  There may have been some inconsistency in the past.  For example, I found this:,

So this is working as designed now?

Hi again @Sarah Krawiec, I saw this today and thought of you:

In Jira v7.10:

"Labels with different cases (cudbear, CUDBEAR) still live in Jira as separate entities, but are now treated as the same thing. When you label an issue with cudbear and another one with CUDBEAR, they’ll both be displayed when you click (or search for) any of these labels. Also, the auto-complete will suggest you all matching labels, regardless of their case, so you don’t create any more duplicates. "

Hi Rachel,

Thanks for sending this along. If I'm understanding correctly, this means that JIRA is not auto-correcting "mLp" to "MLP", but for all intents and purpose, they are treated as the same when filtering/searching/etc.

Is this an accurate summary?

Yes @Sarah Krawiec, that's how I'm reading it as well.  :)

I found exception when you are having some report of Label vs status . all case sensitive Labels are coming separate

With the above in mind, could someone suggest how I bulk aggregate different capitalizations into one label?

I was hoping to search the ~500 instances of the "macos" label and combine them with the ~600 instances of "macOS" with a bulk replace, but of course I now can't segregate these in search!

Makes for a frustrating auto-complete experience.

Thanks in advance!

Hi @Iain McCarthy ,


I had a similar problem but I found a long-winded way of resolving the issue.  BTW I'm using JIRA Cloud, not sure if this would work on the hosted version. 


  1. From your query where you can see all labels "macos" & "macOS" run a bulk select 'Add to Existing' to add the label you want, say "macOS". This will add the label you want to all issues but it will not duplicate the label on issues that already have it. 
  2. From the same query run another bulk change but this time select 'find and remove these' and select the label you want to remove, this time 'macos' 

When you run the query again you should only have the one you want. In this example "macOS".

It works for me. Hope it will help you.


@Sarah Krawiec  This kind of process should help you correct any Labels case sensitive mismatching

This works, but as bulk updates are limited to 1000 queries, and we have more entries than that, still can't remove case duplicates! (Jira Cloud)

Connor Rising Star Jul 28, 2022

Hey @Henry Yei have you tried using Jira automation to remove the case duplicates?

I had not, when I get the chance to work on lower priority issues, I will try and update you.
