VBA ICONS CEASE TO BE RECOGNIZED

I have several large workbooks that get out of sink periodically.  When that happens, I go to the previous month and copy a worksheet from there to the new workbook, the result is that everything now balances out but sometimes my Icons cease to work on a separate worksheet.  When I look at the properties of these icons the property response is that of the page instead of the icon.  Today I added a new icon to replace one on that un-updated worksheet that now doesn't work and found that the new icon was only recognized as a worksheet instead of an icon.  I'm supposed to have an automatic update but it doesn't work either so I updated the software and the new icon is still not recognized in properties as an icon.  What setting am i missing?
