Your image looks hard to watch. It looks your project is WebEdition but not the IOS edition, so I guess it should be related with how you implement the code. Could you please upload the sample so we can reproduce it? Or if you can reproduce it by our online sample, we can download that and follow your steps to reproduce it.
If we don't have a sample, maybe you can share a visit-able website, so we can try to view it in our ipad device. Any necessary steps please let us know to reproduce it.
