Hi, I wanted to change a component's prefix to "A" but when I do that, a small warning popup appears telling me that there's already a component with that prefix. Before doing this, I had another component called A, but I deleted it. There aren't any components with the prefix "A" in the "Components" folder, in the Design Manager tab. I've already tried to close and reopen the project, and to restart the app(I'm using the offline version) Project links: [https://easyeda\.com/editor\#id=\|5b061bbf49a5443095f59906e575f561\|28e031aad7e5495bbdea7c5974e31c4a](https://easyeda.com/editor#id=%7C5b061bbf49a5443095f59906e575f561%7C28e031aad7e5495bbdea7c5974e31c4a) [https://easyeda.com/MyAlexro/arduboy](https://easyeda.com/MyAlexro/arduboy)
