New Captivate simulation issue

When adding a simulation to a project, Captivate changes the size of text and video blocks on preceding slides. Clicking "Undo" removes the simulation slides but doesn't revert the changes made to the preceding slides. The only option is to close Captivate and "Discard" all changes. We've tried creating simulations using different capture types (e.g., fullscreen, application window, and custom size), but the outcome is always the same. Do any of y'all have any tips, tricks, or recommendations for working around this issue?!
