Data for the index is stored in only one shard

Elastic Stack Elasticsearch
1

I am using ES version 7.17, I have a doubt that my index is having settings that it is associated with 100 shards with replication of 2, however all the data for the index is getting stored in only 1 shard.

Please let me know if this is expected or I need to give any more info to understand the situation better.

Hello,

Can you share some evidences like your index settings? Also, how many nodes do you have?

What is the result of the running the following request in Kibana Dev Tools:
