Working with Affinity Designer 1.8.6 on Big Sur 11.0.1 I am having trouble with the Page borders. Opening a document I had assigned page borders before and checking the document settings they show up like not set at all. Then re-checking the button to use page borders, updating a single value and hitting OK will result in all the other values I had not updated disappear. This happens repeatedly. I only get all my page borders correctly if I overwrite each singe value in one session. How comes?
