First of all, the name of the dataset can be different with the name of the analysis. make sure you have validated the name of the dataset in the analysis. you may refer to below screenshot

And there is a chance that the dataset owner didn’t share you the access right on the dataset.
You may not have the right to see all dataset or data source. It depends on whether the owner has shared it with you or not.
