Objects Not Visible Within S3 Bucket for GroundTruth Labeling Job

I am currently creating a GroundTruth Labeling job, and am following the tutorial https://www.youtube.com/watch?v=_FPI6KjDlCI&t=210s . I have created the same bucket ground-truth-example-labeling-job and uploaded jpg files within the bucket. Within this tutorial, under Select S3 bucket or resource, they were able to go within the S3 Bucket and access the jpg files inside.

However, I am able to go inside the ground-truth-example-labeling-job bucket, but no jpg files are visible for me to select. The entire bucket is empty with nothing to select.

Is this a permissions settings problem?
