In the past there have been similar issues with image search returning apparently unrelated or only loosely related items. Disabling lockable filters has helped in the past, but does not seem to help with this latest problem.
If you want to report this to eBay, try shaking your phone while using the app to trigger a submission form, though it appears that eBay is aware of the issue now.
Try image search again later. Possibly after the next update it will work better again.
