Blighted Map search on trade site not working.

Hello, while trying to find my own listings or other listings for Bulk Priced blighted maps I wasn't able to with the options on the site.Is there something I'm doing wrong or is it just not properly supported currently?.

IE: I tried listing 6 T15 Blighted Canyon Maps at 300/6 but I couldn't find them on the bulk site nor did it seem there was many listed (just three).

Thanks.

I think the bulk listings only shows blighted maps at their lowest tier - all the blighted canyons on display are T3
