Thank you for your answer. but I do not know blueprint very well. Could you please tell me a little more descriptive?

Sometimes you can create a new project and simply migrate the blueprint you need to fix from the new to the old project that needs fixed. Just choose to replace it. I would suggest backing up the project before doing so, you don’t mess it up and so you can copy-paste any extras you had in the old project.
