invitation won't send in with new builds

Maybe Im missing something but after creating new build for my app and removing the old one, invitations wont sent to my users that registered at this time. Should i update the build Im sending with boarding? if so, how am I doing it? Thanks!

this is what I see in my group. It shows at the list of tester but it says No build available and invitation wasnt sent.

I fixed the issue if anyone else tackled this issue so basically with any new build you have to go to yout itunes connect account and go to TestFlight>GROUP_NAME>add build
