Problem publishing a report that uses a shared dataset

I have 3 reports that share the same dataset. All reports and datasets reside in the same new experience workspace.

The problem I have is that when I make changes to these reports from PBI Desktop and republish, I get a new version of the report that also has its own dataset. The original report remains unchanged but linked to the shared dataset.

Is this behavior expected? I haven't found anything online yet that describes what I'm experiencing. I'd really appreciate a little help.

The steps I follow are:

1. Open the report in the PBI service and download the .pbix file.

2. Open the .pbix file locally with PBI Desktop and make my changes to the visualizations. I'm not (as far as I know) making changes to the data model.

3. Click PUBLISH, select the current workspace.

Result

- A new version of the report appears in the workspace along with its own new dataset.

- the original report remains unchanged still linked to its shared data set

I can make small edits to reports using the online editor in PBI Service. That works well. I'm just keeping the report.
