Hello, I am doing

carbon emission analysis by using LEAP.

This morning, I modified some parameters

of "Fuels", but when I re-run the model, there is an error notice:

Error:Invalid branch name:"". Names must have at least 1 characters. Branch: Resources\Primary

It seems that LEAP generated a new fuel



automatically, but I cannot find it in the "Fuels"

So, I cannot delete it or rename it, and
cannot run the model anymore.

Sincerely looking forward your help,


thank you !
