Agree. An "intern" is usually a continuation of study, not a
productive team member yet. You need to put more work in or get rid of
them. Love and be kind to them. Help them find a skill, an educational
task no matter how useless it is to you. Forget Jira.
I had to place interns and work experience apprentices once. Most of
the time nobody wants them because they're a damn liability. Someone
has to handle them, and that's time out of doing real work. Even if
you get smart, motivated recruits who are full of initiative, you have
to kinda sandbox them and babysit.
If you're in a big org, apart from that one kid who is the boss's
nephew, realise that your organisation is almost certaily taking them
in as a PR move, or as part of some scheme. The real PR bit that
people miss is that for the next 50 years they'll either praise or
badmouth your organisation, First assignments leave a big
impression. So now you're a teacher. Don't let anyone give them a
broom and treat them as "free labour". Find a task that's challenging
but just within their abiity. Make it really fun, even if that's all
make-believe.
After a year though, it's probably too late to change the dynamic.
