Simbrief no longer calculating even flight levels?

1,000 ft vertical separation (RVSM approved aircraft only above FL 290), only applies up to FL410. At FL410 and above, 2,000 ft separation for opposite direction aircraft is resumed, and only odd Flight Levels are assigned, depending on the direction of flight:

• Track 000 to 179° – odd flight levels (FL 410, 450, 490, etc.)
• Track 180 to 359° – odd flight levels (FL 430, 470, 510, etc.)

Therefore westbound at FL430 is absolutely correct.

Oh wow thanks!!! That is very helpful.
