Working Space Layout is changed (how to reset the layout of the space)

[naoyixue1]

Hey there,

Yesterday, I found the setting of my working space is changed....Originally, I will see report and dataset resepctively on the top, so I can select to see only reports or Datasets in that workspace. (see below)

Now, this is how my space looks like. Do you know how I can set to go back to original version (same as above) Thanks!
