Inconsistent Keywords Upload

cholman

I am having odd issues when uploading a photo including keywords. Using v 1.3.0, Java, Upload HTTP Put with OAuth. Some keywords surrounded by quotes and all are separated by commas. Tried to isolate - remove spaces, no 2 character words.... but cannot fine the factor which allows some through and others not. Receive a "ok" status on all uploads. Read the help for keywords and do not think i am violating any of the rules - except the 2 character item. But the good picture took "tx" without quotes. Please help - i am evaluating and would like to get the upload complete in the next day of so.

Worked: "west point", "usma", "basketball", fassion, people, street, austin, tx
