New Dimension renaming

Hey, I am creating my own test dimension and I want to rename my template, but this error code shows up https://nextcloud.keeeks.de/s/B8GCzMbm6JDQ9mz/preview. It tells me something about a "Ressource Key". Where can I find this key and how can I fix this error?

My folders (I only renamed the noise_settings, dimesion_type and the dimension itself): https://nextcloud.keeeks.de/s/QwRgXk283jZ9Gxq/preview https://nextcloud.keeeks.de/s/B8GCzMbm6JDQ9mz/preview
