session_log does not contain Statistics information

Hi I am using ALVR20.11.1 and I want to use the history statistics like latency and bitrate but the logs say:

11:41:31.230 INFO Client 8428.client: [Warning] Statistics summary not ready!

And the [STATS] and [GRAPH] are empty:

11:41:37.946 [STATS]
11:41:37.946 [TRACKING] {"device_motions":[["/user/hand/left",{"pose":{"orientation":[-0.05758141,0.21218827,0.33082303,-0.91772366],"position":[-0.30668914,0.6977202,-0.86611617]},"linear_velocity":[0.0,0.0,0.0],"angular_velocity":[0.0,0.0,0.0]}],["/user/hand/right",{"pose":{"orientation":[-0.16810232,-0.2498652,-0.524207,-0.7965652],"position":[0.017634995,0.57615304,-0.29410082]},"linear_velocity":[0.0,0.0,0.0],"angular_velocity":[0.0,0.0,0.0]}],["/user/head",{"pose":{"orientation":[0.03658971,0.18495813,0.03534971,0.9814287],"position":[0.024379883,1.0507616,-0.18076341]},"linear_velocity":[0.0,0.0,0.0],"angular_velocity":[0.0,0.0,0.0]}]],"hand_skeletons":[null,null],"eye_gazes":[null,null],"fb_face_expression":null,"htc_eye_expression":null,"htc_lip_expression":null}
11:41:37.946 [GRAPH]

Are there some configurations I missed?

Thanks
