Power BI Dataflow limitation on Datalake

hello everyone,

Just need some advice or confirmation regarding Datalake especially ADLS Gen2 in Power BI.

So, I read this document : https://docs.microsoft.com/en-us/power-bi/service-dataflows-connect-azure-data-lake-storage-gen2#considerations-and-limitations

At the limitation section, it's said Once a dataflow storage location is configured, it cannot be changed.

So, it means if under my PowerBI Dataflow setting, it is said "Your Azure Data Lake Storage Account is connected to PowerBI, and in the text box below it, there is "some name" stated, means someone already create an Azure Data Lake Storage account and already setup my Power BI and I cannot change it? 

Since I was just trying to create the Azure Data Lake for learning and has not setup anything in Power BI, and for sure the "name" specified there is not the one I just created.

Thanks,
