The link to JavaScript certificate is not found

I completed the Javascript Algorithms And Data Structures, solved 5 exercises in the Projects section.
In the Settings page, the section JavaScript Algorithms and Data Structures Projects contains the 5 solutions.

But, I can’t get the certification for JavaScript Projects. The link to it is not found. (below)

The screenshot in my settings page:

Could you tell me why it happens? :sob: I spent a lot of time to solve all JavaScript challenges.

Sorry everybody. It’s my mistake.
I turn off “Make my certifications completely private” in the Privacy Settings.
I turn on it again and my certification can be accessed.
