The number of ground-truth actions does not match the number of steps in R2R_VLNCE_v1-3 gt. dataset

[ZJULiHongxin]

I have downloaded the preprocessed R2R datasets from this official website. In {split}_gt.json.gz, the field 'actions' contains ground truth actions, which should produce the coordinates stored in the field 'locations'. However, the numbers of the elements in these 2 fields do not equal.

Could anyone give me a hint on how to relate these 2 fields? Thanks
