In my homebrew collections there are 3 races called Power. These were subraces that when I made my wifi bugged out and because of this it made 4 versions. I later changed from subraces to making it a racial trait and i could only delete one of them without getting an error code. I am entirely unable to get rid of these 3 and i have even deleted and remade the parent race and the 3 Power races are still there. Is there anyway for these to be deleted as it is confusing my players as they show up as options for character creation.

You need to set the filter to display deleted content and reactivate that original base race. Then you need to edit it and recheck the “will have subraces” box and re-save the whole race. That will reactivate those subraces. Then you should be able to delete those subraces, and then you can do whatever you want with the main race again.

Due to the subraces never actually having any text or anything that hasnt worked, I have tried. It treats them as if they never existed. 

Add text and save the subraces, then re-save the main race again. That should force the system to update its cache.
