Troubles with airport custom kiosk- GC holder

[Nnnniii 0]

I have had a conditional marriage based GC for about 1&half years now. Went abroad 3 times and every time I came back I used a kiosk at US custom but 3 out of 3 times my receipts had a big X on it and I ended up in a long line for the old style custom with an actual person.

Anyone has problem like this?

The reason I can think of is 1. My passport and air tickets have maiden name but the GC is in married name.

2 . I can never get the scan to work on my finger prints at the first attempt. I usually have to make several attempts to make it work and at the end I'm not even sure if it worked at all or it just gave up on me. All I get is the receipt with a big X on it.

I kind of get the feeling anyone who is not an American citizen will get the X and must go through the line. I could be wrong. Another reason could be the name difference.
