This bug isn’t about one specific library, it’s about all libraries that use custom categories. Doing these steps will cause something weird to happen. (footage of me doing the steps)
- Open File → Libraries
- Click on a library that has a custom category (e.g. The streams library), but don’t import it.
- Try to create a new category. The name and color doesn’t matter.
If you do that, not only will your custom category be created, but all the custom categories from the library you selected. There aren’t any new blocks, just the category they should be in.
Also, you can’t add any blocks to your custom category.
Is this a bug?
