Groups don't work when changing intent

[Yahiamice]

I tied a bunch of unusual hat buy orders on my bot manually to a group named "qb".
Upon running !update all=true&withgroup=qb&intent=buy, the bot instead runs intent=buy on EVERY item in my pricelist regardless of group. Why

I use my bot primarily to dump items from backpack sales (on &intent=sell & autoprice) and buy unusual hats around buy orders. Why does it do this?

Upon calamitus's advice, i tried the command without "all=true" and it just errored out

Am i doing something wrong or is this genuinely a bug? I was always advised to use groups to mass update items (i wish i could mass update items of a specific quality to a specific intent too but that one's not possible), so it kinda sucks that they don't even function for the simple feature of bulk updating w/ groups

no clue why but judging from this message i got over a high value item, it thinks the default group is "qb"? what's going on
