I agree - the spots have set off a reaction, compressing the leather, darkening it, making it coarser. Adding more water after it has dried will make the whole strop harder and kill the fine nap. If I was the OP I would live with it - over time the nap is lost/darkened/oil-grease rises to the surface and the whole thing will need some sort of overhaul - wait until then if you can.

Like the Bigspendur says, the droplet marks won't do any harm.
