Some output footage looks washed out. What's the issue?

testing my drone, I shot some stuff in d-log, corrected in premiere pro CC, got it looking pretty good.

BUT when it output it, it looked very washed out, as though the corrections I had set were not actually applied on output.

Brought the same footage into another project also in PP CC, corrected and output, and it looked fine.

I don't know where to start looking. Any suggestions?
Thanks
