Updating Template causes error

When attempting to save an edited template file I get an error:

T 09:16:44.661 ScriptManager: Skipping copy of file ‘/Applications/Toon Boom Animate Pro 3/tba/Plugins/ExportCoreGui/resources/scripts/TB_ExportLayout.js’ because it is present in the user directory: ‘/Users/Carl/Library/Preferences/Toon Boom Animation/Toon Boom Animate Pro/1050-scripts’
T 09:16:44.661 ScriptManager: Skipping copy of file ‘/Applications/Toon Boom Animate Pro 3/tba/Plugins/ExportCoreGui/resources/scripts/TB_ExportLayoutWithMarkers.js’ because it is present in the user directory: ‘/Users/Carl/Library/Preferences/Toon Boom Animation/Toon Boom Animate Pro/1050-scripts’
E 09:17:14.994 Cleva_Rigged is read-only.

Please help, on opening the template again the layers that were renamed are completely empty!

You’ll need to provide more info.

The last line “Cleva_Rigged is read-only.” seems to indicate a possible issue with file permissions/ownership.
