Slot issue in my interaction model

When I click to send my skill to my Alexa account I am getting this error message even though I am not using slots. This happens in both the web app and the Mac app. This is a very simple skill:

Submitting Project Error
Interaction model is not valid.
DuplicateSlotTypeName: Slot type name “capture_slot_YIcGBgTyds” already exists.
Slot type names must be unique.

Let me know if you’re still running into this! I believe we followed up on Intercom.
