Static TRC works on IK but cannot scale model

[Hao Lee]

I am currently working on scaling model with static motion capture data.
The model I am using is

human_only.osim

(591.32 KiB) Downloaded 26 times

However, opensim seems cannot load the trc file correctly, it basically shows the marker data cannot be found.

Yet, the same trc file

static_capture.trc.txt

(246.93 KiB) Downloaded 24 times

can be used for IK. Moreover, if I check Scale Model and Adjust Model Markers at the same time, the error disappear. Is it just a bug?
