can't get multisite copier to work

first why arn’t the plugins in alphabetical order — what a pain in the ass trying to find it

I can not get the multisite content copier to work

I click posts and put in my source site number of 48 hit next step

then I click all the options and I find the post on the right and add item to list and click next step

I then put the destination site in 169 and click next step

adn then it tells me you have not selected any blog
