Why when im using the multi instance wall it only show one window at a time on obs?

I am just getting back into speedrunning and decided to set up julti, which is what I'm using now. Ia assume the main ones are julti and spncer, but I have no clue. I would also like to know how to set it up like Drip120's during his wr.

When Drip120 does mapless in the wr I noticed he had a smaller window to pinpoint the buried treasure, how can I do that?
