When I run first aid, it shows a warning message, what does it mean? What can I do to fix it?
You running First Aid on the Container. This can lead to misleading messages. Try to run it on a volume.
Let us know of the results,

I remember discussions about this on developper and technical forums. No final conclusion as far as I know.
My understanding is First Aid is just a fancy UI for an underlying utility which is in fact a Volume check. Using it on a Container seems inconsistent.
Why it happens? OS updates and migration to APFS may cause it. Some users report that a clean install/reformat may clear the issue. This is overkill in my opinion. Keep in mind they are just Warnings.
Hope that answer your question,
WD
Yes, you cannot conclude there is a problem based on these warnings only. Unless you're experiencing strange issues using your Mac, you can ignore them for now.
It is always a good idea to keep an eye on this type of "issue" from time to time just in case something else shows up.

Thank you very much!
Thanks for your reply WD, run on volume shows no problem. But why Container disk1 will show this message? I don't have this before even I run First Aid.
Thank you! So I can ignore the warning show in container disk1? This waring doesn't mean my mac has any problem, right?
