In-Game Market "Invalid Argument" on min links

Inside In-Game Market, i set filter for min links for Socket Filter - and response is "Invalid Argument"

Same Here, cannot search for any amount of min or max links on any piece of equipment. "Argument is invalid" is returned for any amount of links/sockets requested.

Seems to pertain only to the socket filters tab, and only to the min/max links & sockets. However, I can search for a given amount of coloured links/sockets just fine.
