A350 - Xbox - takeoff performance not computing

[BoeingSpeedbird]

Perhaps coincidence, but since the update two days ago to 1.2.0 on Xbox the OIS no longer computes takeoff performance to be sent to FMS. Anyone else experiencing this?

Please show Screenshots from the OIS Setup while computing the T.O. Performance.

The performance is not calculated if one of the parameters has no valid value, e.g. too short runway or similar.

Thanks. Sorted. My error - runway too short (officially).
