Master slides Randomly Changing

Just contributing that myself and my colleagues also have this problem. When working on a project we have all noticed that the slide layout will change on certain/random slides spontaneously. It's a little frustrating. In our organisation, we can only share to network drives however I can't understand how this makes any impact. Articulate is only opening a saved file from the network location, we run the application itself locally. The spontaneous changes to certain slides (layout changing despite any action being given to do so) very much seems to be a bug within the software itself. This has occurred across all projects I've ever worked on, albeit, it's only been 4 projects in total and has continued to occur across all updates that Articulate has received during the 8 months I've had the application.
