This is a known issue.
There's a small difference in how windows systems display text data. They need a bit more horizontal and vertical room to display text of the same font and size than is required on a mac system. Thus, it's often necessary to open the layouts on a windows system and "tweak" the layout design until all the data correctly displays. Usually, the adjusted layout will display just fine when you then return to a Mac system and open the same layout.
You can reduce the work needed to update or create a layout if you do the work on a windows system and then double check it on a mac rather than doing the reverse.
