I've checked the default pickit and it doesn't seem to be set to pick up whites/blues (that are not 6 socket / 5 link) yet it does so anyway and stashes them.
Please enable "Key Pickup". It's under the Options->UI section. In addition, you'll want to enable "Always Highlight". This info is in the Exilebuddy (SotV) Release/Beta Revision Guide thread, so have a look over that for some other things as well.
