Hi, I'm working on a app I created a few weeks ago, which was functioning just fine, I jumped back in to carry on working with it and I find the data content does not show in the cards. I checked the custom entity that I had created, it was there ok but when I click on the data tab the page just sits there saying loading data... Furthermore, if I then click import data it jumps to the import data page but shows no controls or input boxes. The data I imported was only test data but it concerns me that it looks to be missing..
