Internal 500 error for homebrew races with subraces

I'm  having a problem with  some of my homebrew races. The races that have variants or subraces within them are coming up with internal 500 errors, while the subraces themselves have no problem being displayed. Nothing has changed since I viewed them two  weeks ago, and they haven't been edited in a month or so. I published them thinking that might fix it,  but it hasn't. Any fixes?

Same issue for us. The problem is D&DBeyond doesn't support subraces anymore, so the existing ones have kind of screwed up the website. I was hoping we could delete them, but that internal 500 error is preventing that from happening. Unfortunately, our Homebrew species section is bloated with unusable species. Not sure how to fix it, but let me know if you find a way to delete them.
