brawlex clone tool help!

[funky67]

so i made a clone and decided i wanted to create another. when i hit add i go this error:

Unhandled exception has occurred in your application, If you click continue, the application will ignore this error and attempt to continue. If you click quit, the application will close immediately. Input string was not in correct format

When i hit continue no clone is added and if i hit quit the tool closes. how do i fix this error without losing my clone?
