hello,
just sample and maybe dumb question.
what are these?
Why these are shown on the panel? there wasn't this option on the panel
Is there any problem use aapanel free version?

no, ur good to use it as before
but if you need to use pro plugins, u need the pro.
and blieve me, nginx waf and website statistics are the best,

As the noband guy said, it's only for premium plugins.
