Can't 'ask for DNA' in the future

[Darien]

Staying in the future, I leveled up Science on one of my sims. She is level 9 now, but the 'Ask for DNA' option still doesn't appear in conversations - with future residents and with the household members.
When I go back to the present, everything's fine, but as soon as I return to the future, it disappears again.

Anyone else experienced this?

I havent learned the science skill in the future but have one sim has mastered it in present. He had no preoblem to ask for DNA in the future even to the plumbots as well. Maybe, mine could be a bug?
