screenshots & Debug Log

SUMMARY

I can't get the Adjust Date & Time Plugin work to work.

Screenshots & log attached.

1. I pick the images, 
2. Press Shift CTRL-D
3. The window opens up
4. I set the time/date
5. I apply, it says it processed them without an error. 
6. But nothing changes apart from the Date modified date.

steps attached and the debug log.
The last modified date updates but none of the metadata.

Randomly it will work, but probably 1 in 10 tries. I just figure out why.
