Here is a same issue here you may take a reference to.
A work-around for now:
It will allow you to add a brand new .dtsconfig file
- Right click inside the package and select Package Configurations
- Click Add
- Type in “test”
- Pick any single property in the list and check it (i selected Variables->myVar->Properties->Value)
- Click next
- Type “workaround” for the Configuration Name
- Click Finish
- Click Close
Right-click on the dtsx package and view code (or press F7)
- Search for the word “workaround”
- change the path in “DTS:ConfigurationString”
- optionally change the name in “DTS:ObjectName”
- save
