Issue with displaying hidden areas using variables (all contents within hidden area don't display)

Hi,
I’ve recently come across what I believe is a bug in Figma when prototyping and switching the appearance of hidden areas within the design on and off using a boolean appearance switcher. Areas within the hidden sections are now also hidden intermittently. These areas were all working previously across the whole prototype.

Has anybody else had a similar issue recently with nested layers not displaying when the container layer is being switched on and off using a boolean on/off switcher within a prototype?
