ARCHICAD 21 TEMPLATE CONVERSION ISSUE

HI, Have some questions/issues with converting from Archicad 20 to 21. What is the best way to transfer my working template/favorites from 20 to 21. When I import the template to 21 and open the file, there some icons/items missing, i.e. the stair tool doesn't show up. when I open a file with the standard built in 21 template all the icons show up. Not sure if this is an issue anyone else is having? Please help. I did not find the right solution from the internet.
