TWW dungeons missing when filtering premade dungeon groups by a key range like 3-5

Whenever using a key range expression like 5-7 or even 3-3 to filter the list of premade mythic plus dungeon groups, the list shows only mythic plus dungeons from previous expansions (Mists of Tirna Scithe, Siege of Boralus, Necrotic Wake, Grim Batol), but is missing the new dungeons from The War Within (Ara-Kara, Dawnbreaker, Stonevault, City of Threads).

Using no search expression, a single key number like 5, or text search like fast or tank returns dungeons from TWW as expected.
