Altera FLEX 10K support

[IlyaE]

Hello!
We purchased EPF10K100ARI240-3N but have some questions about marking.
The date code of this FPGA is 1731, but they have ink marking that no accept for ADV1601 (change to laser). 
Also marking format is some strange, because EPF10K100ARI240-3N (DEA561731A) no accept adv9909 PCN, they must DBA marking or no? 

Please, can you answer me its right marking?
How it can be? May be these advisory documents dont valid now?
Look at photo.

Best regards,
Ilya

Apart from that, sorry to let you know that, we do not provide part marking verification in order to avoid the devices from grey market.
