On Screen Spot Question

I own a Flex 6700 and the Spot Flags show up normally on the various slices when using a single PC screen. But whenever I extract one of the Slices to another screen the Spot Flag show much differently. Not only do the normal spot flags get shown, but also many vertical green lines extending from the bottom to the top of the screen, with smaller spot flags attached to them. What is the purpose of these additional upper Spot Flags, and is there a way to turn them off?

Also in the upper right of an extracted screen I see several option boxes (TX, Select, Mode) that don't seem to do anything. Is there a purpose for these?
