With your permission, I recommend to 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.
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 (step by step – Cell by Cell).
Don't forget that not every Excel user has a clue about every job and what you see he can't see.
In this link you will find some more information about it:

Thank you for your understanding and patience
Hope I was able to help you with this information.
