Confusing scenario validation message for collection types

There is small enhancement needed if the user validates dmn scenario with collection data type, being previously simple data type.

Steps to reproduce

• Create new DMN
• Define there custom data type LKW:string
• Set this LKW type for some input data node
• Save DMN
• Create a Scenario for this DMN
• Go back to DMN
• Check tickbox Is Collection for the LKW type
• Save DMN
• Validate Scenario, you will get message as shown in the picture. It can be confusing as it says LKW changed to LKW
