Can't re-do science after revert

[GiantJunkbBox]

It appears that if you do some science, say observe Mystery Goo or take a crew report, then revert and attempt to re-do the same science you get fewer points for it. For example if it was originally a high value experiment it will be lower, if you revert enough it will be zero. I thought it might work itself out when you completed the mission, but it does not.

There is an old thread about this same issue here:

The link at the end no longer works.

This doesn't seem right since revert reverts everything else...

Thanks
