INVALID ENTRY on CRZ ALT

[teofilo 11]

Hi guys, 
I loaded the 747 ready for my next flight and when I am entering the fields into the FMC I got to the CRZ ALT field which always works and when I enteres 290 for my flight level I got a INVALID ENTRY error message.

Tried different altitudes and none of them worked.

Why would I get an invalid entry if I am entering the altitude correctly?
I also tried 29000 and still same error.

Thanks in advance.

Perhaps you want to enter 290S?

Hi, it was an imported flightplan file from Simbrief that caused the issue apparently I entered it manually and didn't receive that error again.

Strange that it worked with a previous flight almost at max weight as well.

The flight was from VHHH to PANC, weight almost at max.
