Hidden sheets not hidden on Mac?

[mrawson]

We recently built a spreadsheet containing several hidden and protected sheets. It was built this on Windows 10 PCs running Excel 2013. When someone else opened this spreadsheet on their Mac (I don't know versions of OS or Excel) the hidden sheets were all visible.

I've heard a rumour this is a known problem, but couldn't find anything obvious via Google. Anyone know if this is true, or is it more likely human error?

Thanks.

hidden or veryhidden, any hidden sheet is visible on a right click on the tab
