If you're a member of a trusted traveler program, the name you use in the traveller info. section on your online profile (not necessarily the same as the name on your ticket) must match exactly to the name as you use it with Global Entry (as printed on your card). So if you have a middle initial on one, and full middle name in the other, it will cause a mismatch and deny you.

If it still isn't working, I'd suggest even taking your GE number out of your profile and seeing if that works better for you. If you fly every week, there is a good chance you can get it without the trusted traveler status appended. My wife, a premier silver, never got the three beeps while her GE number was in there, I realized because she is a Canadian Citizen (GE through Nexus) and you have to be US if that is in there. Finally, I took it out for her, and we both got take advantage this weekend.
