Variables are displayed twice on Process instance variables page
On the Process Instance Variables page, the datatable displays twice the columns: `Name`, `Type` and `Value` and the process variables are listed twice.
Steps to replicate the issue:
1. In modeling application -> Import the project attached -> Release the project
2. In Admin Application -> deploy the release
3. Navigate to Process workspace and Start a new process
4. In Admin Application -> Process Admin -> Process Instances -> filter by the application name (rest-json) -> go to RUNNING Process instance Variables page
Expected result: `jsonResponse` and `url` variables are displayed only once
Actual result: Both variables are displayed 2 times and `Name`, Type`, `Value` datatable columns are doubled (see screenshot).
Able to see Name, type, value column only once on variable page.
