I know this is probably related to data coming from Scryefall, but prices in the main War of the Spark are mixed up between main set and Japanese alternate art prices (example below). As you can see the foil listings for planeswalkers are defaulting to the alternate art prices (and if you try to launch out to something else it takes you to the alternate art listings instead). Is this an issue or just something with how combining things is effecting the filter?
Ok now I can repro then
will be fixed in a hour or so
