Schedule FSI - How to update capital loss as my 'Income from outside India'?

I have made short term loss with my investment in US shares. I am showing these losses in Part B- TI of ITR-2. 

But in Schedule FSI, When I am trying to enter a 'negative' number as Capital Gains under 'Income from outside India', it is not allowing negative number. 

Can you pls let me know how I can show loss under 'Income from outside India'?. Thanks for your support.
