Duplicate Data From Sharepoint Folder Link

I have managed to successfully set up a data model that updates based on files in a Sharepoint Document Library, however I am finding that the data is all imported twice.

I presume that this is because it is seeing the Tables as one data source and the Sheets as a second, and so is pulling in both at once.

I have managed to work around it by filtering out Sheet1 in the data table name, but that won't work if it is called something else.

If I was connecting to the workbooks directly it would be easy enough, but as I am just connecting to the folder I can't see a way to do it - Is there an easy way to only pull in the Tables but not the Sheets?

Thanks,
Alex.
