Translation:My daughters' children are my grandchildren.
I think "great grandmother" can be "mormorsmor," "farmorsmor," "farfarsmor," or "morfarsmor"? "Maternal grandmother's mother," "paternal grandmother's mother," "paternal grandfather's mother," and "maternal grandfather's mother," respectively?
Also, "great grandchild" is "barnbarnsbarn," or "grandchild's child." I think you add an s after each set of two, so long as there's another word after it. Mormorsfarfar, barnbarnsbarnbarnsbarn, farmorsmormorsfarfarsmorfarsmor, etc.
I might be wrong, though, I'm still pretty new at this! Sorry for any misinformation!
Unfortunately, the word bank is generated automatically and Duolingo is pretty bad at plural apostrophes, so it's nothing we can affect as contributors.
That said, we do accept "The children of my daughters ...", so it's also possible the word bank was trying to get you to put that. :)
Is the problem mainly on mobile devices? I haven't experienced that problem on my computer. This sentence is displayed correctly. I just looked at the discussion because I had missed that it was daughters and not daughter the first time around. My mistake, not Duolingo's.
No, not as far as I'm aware. We literally have hundreds of comments - and thousands of error reports - all over the course regarding incorrect English because of incorrect plural aposteophes. I'm glad to hear it's working for you, though! Maybe they finally fixed some of the issue.

It's probably not very meaningful to know whether their your daughter's children or your son's children. Especially if you have several daughters and/or sons. The same is not true for uncle and aunt, since you normally only have one father and one mother (but that is going to change, obviously).
