Hello. I was able to add link before. But I joined the translation group and I couldn't add the new version of chapter 1 with new group.
we simply don't list the same chapter (from the same translator) twice, despite what group they joined afterward. we'll only replace the old one, if it is dead, or was requested. (and for that, you'll have to use the Report Problem button on your profile page. DO NOT use the Add Release page for fixing/update chapter request)
