Overlay is disabling hotspots?

I have a basic prototype where clicking the hotspot on Screen 1 (Subsystem): 1. navigates to Screen 2 (One item), then 2. opens an overlay.

I have a hot spot on Screen 2 to open a second overlay, however it’s not even clickable if I’ve started the prototype from the beginning. If I run the prototype straight from Screen 2, it does work. Is something about the first overlay interaction breaking the hotspot on Screen 2?

(More screenshots because new)

When you start from screen 2 there is no instruction to open an overlay. You can add an interaction in the screen 2 directly to open the overlay after certain delay

In the second screenshot in my comment, there is an interaction to open the bottom overlay.
