I can't duplicate a space on zerogpu

Hi I am new here. I have a pro account. I was trying to duplicate a space that require zeroGpu

I get the message that I have running 10 spaces on zeroGPu. I was only running one, and I put that to sleep, still same problem.

Please advise what should I do.

regards Javed Alam

Thanks

delete one of your spaces. it has a max of 10.
