With your permission, if I may recommend, provide more information.
You'll get a quicker and more accurate answer, and those who want to help don't have to invest time guessing the problem.
What I recommend: Always inform about your Excel version, operating system, storage medium/hard drive, OneDrive, Sharepoint, etc.).
If possible, add a file (without sensitive data) and use this file to describe your project step by step, or add photos with the appropriate description.
Don't forget that not every Excel user has a clue about every job and don't forget that what you see he can't see.
In this link you will find some more information about it:
