During October the custom fields - checkboxes were shown as dropdowns which one could click, expand and choose. However the last weeks we have noticed that the checkboxes are shown directly as text, during the creation of the issue

and as dropdown during the edit of the issue

I tried to check for a new release on jira cloud that might show this change but I am not sure what is happening. My custom field is set to have search template as "multi select searcher"

Anyone observed a similar change or is aware of how to set this back to have a dropdown during the creation?
