Thank you for the detailed information.
Indeed, I was able to reproduce the unexpected behaviour when a floating image is inserted in the header of the document and its content is edited later. I've already logged this in our internal bug tracking system. Unfortunately, I cannot commit to a specific timeframe when the fix will be available. For now, I can suggest you to
follow the related item
in our feedback portal in order to be notified about any related changes.
As a workaround and as a different approach to achieve the desired goal, you could insert different sections
in the document and to set different watermarks
(depending on the image) and properties (page margins, page size and etc.) for those sections.
Sorry for the caused inconvenience.
In appreciation of reporting this, I've added some Telerik points into your account.
If you need further assistance, please get back to us again.
