The cells on the sheet that can still be edited are probably not "Locked".

Select one of those cells and use Format -- Cells and go to the
[Protection] tab. If the check box next to "Locked" is empty, it means that
the cell may be edited even when the sheet is protected.

I have a problem with protection tool in excel. I set protection to
worksheet, but it had not applied to whole sheet. Some parts can still be
editing. Why protection does not applied to whole worksheet? How can I fix it?

Could you help me please?

Thanks,
