The CLT panels in the FEM-Design library are based on the Martinssons products. We recently became aware of some changes in properties of their products, hence with the newly released service pack, library of CLT panels is updated.
The new timber panel types are available for users only if they choose "Reset" settings when starting the new FEM-Design version.
Otherwise you should manually delete shellpaneltm.fdl file from the following location: C:\Users\[user name]\AppData\Roaming\Strusoft\FEM-Design 16\FEMData\[code directory]
