Sheet Zooming to 400% when opened?

I am working on a project with several sheets.
I have coded the sheets to zoom to a specific cell length when activated, and it has been working fine.
Yet now one of the sheets when opened immediately zooms to 400% (maximum) and I can't figure out how to stop it..
Is there a way to stop this from happening?

I would go to the sheet that is at 400% take it back to normal then while in sheet 4 save the workbook. see if that works
