DIVI 3.0 and Hummingbird

I am putting together a site and I am very keen to use your plugins. However, I use DIVI and have just updated to v. 3. I discovered my lazy loading images on headers and the percentage circles on the case studies pages stopped showing. I deactivated each plugin one by one and found after deactivating hummingbird the images all show correctly. I am not highly tech – is there a setting which might be causing this?
