John, if you look at your Changes Log, you will normally see the definitions were created and attached to the profile, but then were removed, probably by accident.
As another example of a profile that was created by a Gedcom, which is different than the one that Dennis referred to, check each entry in the Changes Log for Sydenstricker-52 by selecting the 'Created' or 'edited the Biography'. You created that profile Dec 2018 and you can see the ref names were defined at the top of the Biography with the Name when it was created. On the Next Change, you will see on the left side of the Changes Log that you removed all of those initial references for the name because the right side has that section removed. I fully understand doing that with the Name field, but that is what caused the problem in that profile.
You can copy each one back from the Changes Log and add them to the biography in one of the areas where each is being used. If you need additional help, send me a message and I can help you.
