Formulas stop updating when page is zoomed?

I have a multi-page workbook, and am using check boxes that - when checked - update a dollar amount. The formulas I have used work fine, until I zoom the page, then the check box farthest to the right stops updating when checked or unchecked.

It is a multi-step formula:
check box (in column J), to the cell the box is linked to, to a hidden sum box (in column A), to grand total sum (located at the top of the spreadsheet in a merged cell A-J).

The formula always updates in the sum box (A), but stops updating in the total sum when the page is zoomed so columns A-C don't show.

Any ideas? This is going to be used by consumers, and needs to function properly at all times.

I can see your point The full workbook is too big - I pared it down to just the problem portion. I think it's attached...? It is the Appliance 1 page, the last item.
Again - when you zoom in, or scroll to the right, the formula up top stops updating

Thank you!

Do you have access to a different pc that you can test on?

I have just tried zooming in, zooming out, scrolling, etc. and the checkboxes all appear to update their respective formulas correctly.

I have to go AFK for a couple of hours, will look into it more when I get back.

I will have my bosses try it today at work on their laptops. Thank you.
