Stock fork springs are progressively wound, tighter (closer spacing) at one end, looser at the other end.
Progressive brand fork springs are uniform pitch, and shorter than OEM springs. A spacer is required, and provided.
Why/how you have a spring, spacer, then shorter spring is beyond me. But I will have to assume the previous owner installed some sort of aftermarket (Progressive?) fork spring.
The damper tube appears to be stock, so I can rule out Race-Tech Cartridge Emulators.
As to removing the fork cap, I hear ya! On the Concours, it's 3/4" of compression, max.
Edit to add: your springs are in all probability a Progressive (or equal) upgrade. The shorter spring fits over the damper tube to eliminate shock when the fork is fully extended. The metal spacer generally goes on top of the main spring, to prevent the spacer from rubbing the fork tube during fork movement.
In a nutshell, you're fine
