ADA Compliance - alt text flagged as missing

Hello,

I’m running my site through WAVE WebAIM and am consistently getting an error for “Linked image missing alternative text” but I added alt text and I can clearly see it in the code. Can someone tell me what I’m doing wrong? Thank you.

If I remove the Interaction > Navigate to Page, it becomes a standard image with alt text and is not flagged by the compliance checker. However, the point of the image is to be a secondary link to that page apart from the regular navigation menu. Is there a way around this?
