Figma Slides: Locked graphics moving around, page number not updating when duplicating/ moving pages

I have encounter 2 problems that frustrates me when using Figma slides.
Background: I made a template for me and my team to use, and have set up a footer as locked graphics, and included a page number count text box within the locked graphics.

1. Sometimes when we come back to the slides after a while or even while editing, 1-2 page’s element will be moved around/ missed align to original design. We will have to manually re-organise them again.

2. When duplicating pages or moving a page around, the page number count does not update. We currently can only add in a new slide and copy the old page’s element into the new slide.

Is there any solution or is it the current limit of Figma slides? Should we just stay using Design file for presentation.

Thank you.
