Review page not responding to specific vendors

Hi Ladies and Gents

I’m busy building a community food app, the app is 2 sided with Users one side and Vendors on other side. I am currently building the review page, but been struggling to reviews to stick to the specific Vendor, the reviews pops up across the board. What could the issue be? I watched all the tutorials, I have redone the data structure over 4 times, the list is filtered to logged in user posts, any ideas?
