About label exchanged incorrectly

[SHIELD-Ma]

Hello, sorry for the disturbance.
I have some questions related to this dataset. It seems that in some examples the GT is labeled incorrectly as shown below.
(the shown example is S1_session2_mov6, the point hipL and point hipR might be exchanged by mistake)
As far as I know, S2_session4_mov5(elbowR and handR) has similar situation.
I wonder if this problem exists in the Vicon data, or it is caused by the processing code.

Thanks for your reply!
