I made the Settler test even more fool proof user friendly: It seems that some users could not find the radio button on the lots to select a lot. Now, instead of having to click on the radiobutton, you can click anywhere on the lot to select the radiobutton.

On top of that, the “next” button on the top changes to “Choose lot EMP_A1” or whatever lot the user chose. I hope this will reduce the questions.
