[RTTY] WARNING - Entry class for LDC RTTY contest

[Roman Loparev]

The similar problem with SOAB log.
Have an auto response from the contest robot:
 

your callsign: VK5NPR/3

your category: A1 (SINGLE-OP) (*)

your contest:  LDC-RTTY

number of QSO: 39

 

(*) The Subject line in your mail does not contain the catogory.

 

There appears to be an error in your submission: please check the rules
carefully once more, make the changes and re-submit.

This will replace the previous submission automatically.

 
But I've done my log as per LDC Cabrillo format on web-site. I am using the
following header:
 
CALLSIGN: VK5NPR/3
CATEGORY-OPERATOR: SINGLE-OP
CATEGORY-OVERLAY: NONE
CLAIMED-SCORE: 181908
CLUB: VKCC
CONTEST: LDC-RTTY
 
Tried to submit my log 4 times and changed CATEGORY-OPERATOR line to A1 and
SINGLE-OP A1 but anyway had the same robot auto replay message with an
error.
What am I doing wrong?
 
73! Roman, VK5NPR/3 (ex. UN5PR / UP5P)
 
-----------------
The LDC contest robot did not recognize "W4UK SOAB-6" as a 6 hour 
entry. Had to spell it out as  "W4UK SINGLE-OP 6-HOURS", which is the 
format stated in the LDC rules.
 
No shortcuts allowed.
