Accessibility issue with duplicated alt and aria-label – WAVE warning

Hi,

I'm working on improving accessibility on my website and noticed that the WAVE accessibility tool flags multiple images with the warning “Redundant link” or “Redundant alternative text”.

https://riko-meble.pl/realizacje.html

I’ve attached a screenshot for reference.

It appears that both alt and aria-label attributes are set to exactly the same value (e.g., "Meble na wymiar Warszawa"), and WAVE treats this as redundant content for screen readers.

My questions:
Is this a real accessibility issue, or just a false positive from WAVE?

Is there any way to modify or disable the automatic aria-label assignment in your extension? I couldn’t find such an option in the module settings.

Should I be concerned about this from an accessibility compliance standpoint (e.g., WCAG 2.1)?

Thanks in advance for your help and clarification.
