Duplicate entries in intents or slots
Problem
Cannot delete duplicate entries in intents and slots.
Duplicate autogenerated slots don't have a delete option.
Skill Publish error states duplicate entries.
Exporting and importing all the modules will not generate duplicate intents or slots.
Duplicate autogenerated slots get created when importing the modules in parts.
Solution
When importing the modules in parts, make sure that you import the intents&slots module in the end.
