Hi guys, so I'm having some issues with a file I made. It seems to be having issues running on Excel 2013 as I created it on Excel 2010 and I am unsure if there is a way to fix it so any assistance would be appreciated.

The sheet was created in Excel 2010 and should look like the below:

However, some Excel 2013 users are finding that the sheet displays like the below:

Everything is still there (buttons can be clicked and will have their function) but for some reason they are not displayed and it instead shows the cells underneath.

Is this a known issue and is there a fix for it?
