Very strange behavior.. you might try:
- &tplFirst=
Home
- &depth should be an integer, unlikely, but could cause problems
- check to make sure your first resource is published and not hidden
by default I believe getResources sorts on menuindex - check your indexes [or specify a sort order explicitly - you can't always trust the order resources appear in the resource browser, it may be cached or set to not update on save]
Kind of looks like you are trying to build a menu/navigation, WayFinder will not work for you?
and as always, always-always clear the modx cache....
