Dynamic default for Parameter always shows ALL

I want to Display the Value from the specific dataset in the Title of the visual.
I created a new Dataset that has only 1 row, and then created a Parameter with a dynamic Default Value is the column from this dataset.

And then set the “Reserved Value” to Recommended Value.

And in Visual Title I have
Riskiest User : ${UserName}

In Analysis this gets displayed as “Riskiest User: ALL” And the same when I embed this dashboard.

The user name column needs to be pointing at your or the UserName of the person logging in.

Is the username column in your dataset your username?
