I spoke to Technical Support about this just now and was asked to submit a screen shot. I hope the attached screenshot displays properly. I am using an iMac with El Capitan. Safari is my browser.
How exactly did you get to that that account set up page? Can you list the links/options you clicked
The weird thing is that appears to be part of Trimble Connect profile completion pages. You should not see those if you are creating an account from SketchUp or SketchUp related properties like 3D warehouse or Extension Warehouse.
