light room bursh

Would you mind elaborating on what's happening and what you're trying to achieve? Also, please share the application version you're working on along with some information about your computer. 

Looks like you're on a Windows machine, so you can go to the Help menu in Lightroom, then System info and copy the text. You can paste the text here as a reply. 

We're here to help, just need some more info! 
Thanks,
Nikunj
