Repeater Issue

Ok, this is now driving me nuts. So I have removed the dataset. The repeater items are populated via the query (or at least they are meant to be and are some of the time)

Case test 1: Hit the url; https://foylecycling.wixsite.com/mysite Most times the default repeater images/text appear. Keep hitting F5 and eventually the correct data appears. Hit F5 again and the default data might appear again

Case test 2: Hit the url; https://foylecycling.wixsite.com/mysite Browse to another page e.g. Foyle 3 Day Race and then click on Foyle logo to return to home page. The correct data appears every time but hit F5 and it will probably be replaced by default again

Case test 1 and case test 2 are on live. If 2 always works, why is it that case 1 usually doesn’t work?
