Hi @mengchaoheng,

It looks like you are doing the replay of a multi ekf flight log.

The documentation says: The recording and EKF2 replay of flight logs with multiple EKF instances is not supported. To enable recording for EKF replay you must set the parameters to enable a single EKF instance.

So you have to set the parameters as described here.
