I see this bug is old, and it stills remains here.
I solved using info in this old post.

But it is not fair to have to replay a mission, just for a bug.
"I was playing the Devidan missions and the system won't accept the solution to calibrate McCoy's cortical stimulator. I looked online and my imputs were right. I've logged off and on and beamed out and back down to reset it. So far it has yet to accept. He just says let's try it, and it didn't work no matter what I choose".
Could you please fix it?
I did this:
I followed the suggestion listed in this post how to complete this part. You have to give the calculations to McCoy while he is still walking around. So you have to be fast to scan the 2 other crew members to get the correct calculation, also have to click thru all the choices after you scan them. To get McCoy to reset I had to beam out, and start all over.
Just reporting this bug.
