This is already known to me.
It happens to all L2 styles I converted over from Lemmini (Shadow, Egypt, Sports, Castle). The trigger areas are misplaced, because the resolution needs to be altered from Lemmini to NeoLemmix format. Usually the sizes for the triggers needs to be doubled to get the NeoLemmix fomat if I remember correctly.
I don't know: When I'm making the single-colored background update in the future I can try to make the sets again from scratch as a exact duplicate with NL format from the start on (of course only if this doesn't affect levels that have already been made + would be quite some work again
). But I dont know if this will work
Maybe only the objects need to be remade, but this needs to be tested out (Had some trouble with the conversion back then and was just happy it worked at the end
).
The trigger areas that are misplaced
could also be an editor bug that misplaces from Lemmini converted trigger areas.
