Kalguuran Scarabs don't appear to be listed on bulk trade page for trade site.

Quite a simple issue: the 3 types of Kalguuran Scarab don't appear to be listed on the official PoE bulk trade site as an option to choose when looking for bulk trades (https://www.pathofexile.com/trade/exchange/Mercenaries). They ARE in game for the in-game currency exchange, but there is a hefty gold price associated with bulk buying scarabs that I'd rather avoid, so went to the bulk site to try to buy them manually, only to realize they don't appear to be an option there.
