hiding rows which contain checkboxes but checkboxes don't hide as they should

correct, this is after the hide "test" macro has been run.

This is showing my view of the issue i.e. when the rows are hidden the checkboxes that were in them aren't always hidden or only partially hidden.

easy way to see my issue is if you manually hide row 39 in both sheets. In the first sheet the checkbox remains, in the second sheet the checkbox is only only partially hidden but still visible

This is why I suspect this issue relates to a setting rather than the code itself.
