Labels in search is not retrieving based on case sensitivity

When you navigate to a project > labels, there are labels shown are various cases: All caps, mixed case, all lower.

However, when you click on them to locate those, the search does not display based on case sensitivity. So, I clicked on mixed case, the query is correct; but, the results shown don't match the query. The results are showing all values, regardless of case.

I need it to show the results for what is being requested.

Attached is the screenshot that shows the labels of ATLAS, Atlas, and atlas.

The other attachment shows that I clicked on the label of Atlas and the query is correct; but, the right for one of the issue details shows that it has the label of ATLAS and not Atlas.
