Hello, such a question! Why, when I create a new page in LayOut and copy models from the old page to it (using ctrl+c), the models are copied overlapping each other? That is, I click on the model and delete it, and it remains again.
Can you share the LO file so we can see what you have going on?
Load the link, where you can see, how the model is not deleted, it seems to be layered, Therefore, the file layout is very buggy. https://vk.com/video166311965_456239162
Please share the LayOut file so we can see what you have going on. The link you provided requires that I sign up to be ab le to see your video.
