After I complete the Cambridge Polymer Labs quest, the "Complete the research project" task is marked as FAILED in the quest summary in the Pip Boy. Is there a way to avoid it failing? Did I do something wrong or is it a bug that can't be resolved?

This should be posted in hint, cheats and spoiler. It's a known bug due to wiki. Ignore it. If you got what you came for, no problem.

Cheers,
