Future candidate labeling does not show in filters or create new lists in boards...

Summary

When attempting to search in a board for candidate labels beyond %15.1, a user is not able to select those values from the dropdown. Though they can type the value in and search for it, it is not intuitive to the user that the value is possible to search

Steps to reproduce

  1. Navigate to a board
  2. Type on Label=candidate::15. and the dropdown should produce similar to below: Screen_Shot_2022-08-23_at_12.52.11_PM

Additionally, when attempting to create a new list in a board:

  1. Select Create List from board.
  2. In options box, select Label and search for candidate::15. and the dropdown should produce similar to below:

What is the current bug behavior?

Besides candidate::15.0 and candidate::15.1, no other candidate labels display in dropdowns to use.

What is the expected correct behavior?

Dropdown should produce all 15. candidate labels that have been created and used in GitLab so far in the gitlab-org project.
