OK, thanks. Unfortunately there is nothing wrong with that data, and I can’t reproduce the problem. However although I have tested them on Safari, that is the PC version not the Mac version, so the tests are not conclusive. However, I can’t think of any reason the browser would make a difference.
The problem you have is that as it’s the Family tab, if there is a data issue it could be with any member of the family, bot just the primary individual.
It could also be a server issue, though it shouldn’t be.
Can you give me a screen shot of the failed tab, and if possible a text file containing the page source from it (on a PC that means right-click anywhere on the page; select “View page source”, then copy/paste the result to a text file). Hopefully the process is similar for a Mac.
