Cannot select the destination website in Multisite Content Copier

I have a network of sites and I was trying to copy the home page of site “id=1” to “id=5” but I get the error Site with that id does not exist.

I tried adding the site by using the url also but in vain. I even tried purging the cache. Please help.

I used “Broadcast” to do that and it worked perfectly fine.

Please assist.
