q- d- currents of PMSM drive in Delta configuration

I measure the line-currents of a Delta-wired 3 phase PMSM (SimScape).
Then, I apply the Park transform to transform abc to dq0.
Now, the output of the Park transform is different from the d- and q- currents that I see in the SimScape result explorer.
When I switch to Wye-configuration. The values are as expected, but the torque is higher than what I would expect from torque = K_t * i_q.
Notice how the idq0Scope (after Park transform) gives different values. (d/q; 10/0 vs 5/-2.887A)
Can anyone explain this difference?
