You can ignore that error message as it doesn't apply to your implementation. However you really need to fix a load of issues with the other aria in your example.

This is probably not going to cause any issues in your implementation, but there is a good reason this error is shown.

Generally if you use multiple checkboxes with the same name attribute you are submitting that information as an array of options. As such it is expected that these checkboxes are related to each other and so should have a common naming.

Using aria-labelledby allows you to associate more than one label. So you would have the "master" label (say "meal options") and then a checkbox specific label (i.e. "extra sauce" or "extra chips").

That way when a user reaches that group of checkboxes they know they function like a multi-select and are related. This is why Axe recommends this as it thinks your inputs should be part of a list of options as they have the same name.

Here is a simplified example with just the key attributes to illustrate this behaviour. The first input would read "Meal options, extra sauce", the second "Meal options, extra chips".
