It’s a fairly minor bug as I can just leave the game and come back to fix it.
After redoing a timeline and replacing my blessing the description of my old blessing persisted on screen. Open and closing parts of the UI such as my map or inventory didn’t seem to fix the bug. The specific blessing I replaced was increased rune drops and the blessing I replaced it with was increased unique drops. I will reply if I experience the bug again.

Also I found this old thread that is probably about the same issue but it was closed so I could not reply to it: New Blessing Bug
