Hi GentileP,

The quick answer is you need to consult with your Sage business partner.

From what version did you upgrade from? 

Can Admin see the customizations but no one else? If so, access the Apply Form Customization and choose the appropriate Level for Company, User, Group. Hopefully this is the issue as it is the easiest to address.

Next, review the data bindings tab for any customizations you imported. Are these tied to Schema that changed from the prior version? Rework to the current schema and rebind.

Is there custom VB scripting attached to the customizations? These likely need to be reconfigured for the current version. 

One possible approach which can be helpful. Presuming you have several similar type changes. Delete one and recreate it from scratch on the current version. Then compare this to a non functioning customization. Can you determine what is different?
