I'm doing a long-play Sandbox mode game, and suddenly around day 215 I've lost the ability to see most of the details that appear under "Basics" for my slaves.  All I can see is Basics: [Name], [Species], [Age]  see below:

I'm not sure exactly what could have caused this.  I did recently edit my save to change my player-character's tattoos, but this didn't crop up for at least a couple in-game days after that.  (I went back and checked the saves immediately after the change and everything is fine.)  The other thing that leaps to mind is that maybe I've just exceeded some maximum number of slaves.  (I'm using the Supporter Section option to massively increase my capacity.)

I can still see all the stats by using Mind Read, but that will get old in a hurry.

Has anyone else seen this issue?  Any tips on how I could fix it?  

It's a feature not a bug. Text that has a line under it is considered a URL(a hypertext link in other contexts, but it is called that for its BBCode) or text that functions like a button. The lead text of each section has the function of toggling the visibility of that section. For example: https://itch.io/post/1048253
