Leading spaces in repeater is removed when adding more conditions

Trying to build a simple tree-widget but cannot figure out what’s wrong. I indent by just having a column with spaces, and it works if there are no other Item loaded events, but fails when there is. See example file. Wondering if anyone have any idea on how to fix this in another way? I want to be able to add more Item loaded events but get the visual presentation to be as in the right repeater. In Axure both render correctly

Think I found an acceptable solution, note that the idea was never to have a fully featured tree widget but rather just have a repeater to look like one. Really hope the standard tree widget would get some attention…
