Got two `Book` models when created a new project manually without upload

[dgleba]

I just made a new project and added a model Book by typing in the name Book, not using the upload button.

The picture shows the project name and the two Book models.

Hi @dgleba

Thanks for the report, it might be a bug where the button is not debounced so could be clicked twice in quick succession.
I will check if that might be the case.
