Fixed WTB/WTS overview not filtering correctly

1) Begin creation of a new trade
2) Mark trade as WTS (defaulted, left this untouched)
3) Click the button to show all WTB offers in a new tab

Result:
It actually showed all WTS entries, rather than WTB. Potentially just "all entries", wouldn't know that since I don't know if there even were any WTB entries.

Edit:
Found something that had "WTB" listings, seems it just doesn't filter at all so rather than seeing only WTB, you see everything.

Know about this bug, thanks.
