Crowdin: Different versions of same documents appear concurrently under a file

Theoretically, documents on the Crowdin project page should be identical to those on the doc site. But now you will find different versions of the same documents under a file. For example, under the "get_started" file, index.md should have been deleted and replaced by hello_world.md.

How can we ensure that the Crowdin project is promptly updated along with the doc site changes?
BTW, we are now using Crowdin CLI 3.6.0, while the latest version is 3.10.0. Do we need to update the tool?
