Renaming a schematic symbol

I started drawing a schematic a few weeks ago and at that point I was able to rename the symbols I inserted into the drawing like circuit breakers as well as a motor symbol that I renamed to include a specification. I opened the drawing today and now I cannot edit these symbol names at all. I can only move the text or change the font. Double click on the text does nothing now. I also tried a new drawing and I still cannot make this change to a symbol name. For example, when I add a symbol like a circuit breaker to a new drawing it would be default labeled as CB1. I cannot change that symbol name and I could before. Why? I have a work around for this which would be to just add a text box and change the symbol name but I am sure there is an easier solution to this issue. Any help with this would be appreciated. Thank you.
