@Oanh-and-only-Oanh this seems like backend api issue https://api.topcoder.com/v4/challenges/15948

from James, "This has nothing to do with ui or v5. This is data that is stored in a spot that we weren’t migrating from because I wasn’t aware it existed. I’m working with thomas to do the one-time script to migrate this data forward. Once that’s done, it’ll be part of the v5 roll out. if the data exists in v5 once it’s migrated, then it’s gotten just like any other challenge details request."

adding this issue to deployment roadmap. High priority.
