Ch1 FM 6 Top Level

There's a spot located a little to the right of the edge of the top level of FM 6, where no one can open a store. Can anyone shed light on this issue?

I don't play in Broa, but I'm guessing someone jumpdowned RIGHT as they were opening the store, so that the store is technically there so that nobody can set up a shop, but the store is actually further down. I know you can do this with omok sets and getting hit, at least, as well as jumping down right as you sit on an environment chair.
