Hello, Anyone could help please? Thanks.

Here is another view.

Yeah I just deployed it and it deployed successfully, might be a bug with the metrics?

Thanks so much for testing!
Do I have to add or configure something specific for the metrics?

Nope. In my experience it's just based on the success rate (as reported by the railway service being able to actually deploy) of your template on recent deploys.
I've noticed, especially with new templates, sometimes these metrics are off for the first few days. Usually they level out.

I feel your pain though. I've had templates drop down to 60-70% for a day or two then come back up.

Thanks Mykal for your answer, and thanks for feeling my pain.
I feel pretty sad about it because it feels like saying my work is bad and that my template shouldn’t even be installed. It has never been anything other than 0% either since the begining (it is not new anymore).
I would love to know what Railway can say about this.
