[RTTY] Problem with WAE log upload robot - OM2015TITANIC

[Don AA5AU]

I worked OM2015TITANIC in the WAEDC RTTY contest and sent it as a QTC. When I uploaded my log, the robot rejected it because of this line:
QTC: 21113 RY 2015-11-15 1344 DH8WR         5/10       AA5AU         1317 OM2015TITANIC 265 

I don't see anything wrong in the line other than perhaps the unusual callsign OM2015TITANIC. I've sent email to the contest manager for clarification. Anyone else having this problem?
