I'll try a different device, but on iphone6, I reloaded and searched again several times (only search term is 2015) and got the same result...
The small images match the listing next to them about 60% of the time... And it seems to be the same items getting this error, so I'm thinking a table error, or some slight distinction in those images, handled differently on display, rather than something transient.. If it'll help, I have gathered screenshots.
The DB is great, btw, this was just an odd error i (barely) noticed, hardly a major issue.
Ok, update., tried same search on an iPad and it displayed correctly, same iOS. Perhaps it is just an iPhone 6 issue, after all, and I am blissfully ignorant of iOS coding
