Online Checkin - Strange Behaviour

[Colster]

Just checked in for a flight tomorrow (syd-mel) and got assistance required for 7A - Change of equip / Cancel flight or Op Up??? Thoughts?

I have had that so many times, as I chop & change my flights around quiet often, sometimes when the original ticket is turned into a voucher or you have changed the booking a few times it requires you to get help.

Dont know why, but I seem to get that same answer a few times when I ask "why"

I too am having strange behaviour from OLCI, with it not allowing me to do it, despite being on a Mel-Syd-Ool/Bne-Mel status run.
It just keeps showing "Booking" as the next flight segment. Is this normal, or does that imply I should seek assistance?
