That's a pretty classic expat experience--something familiar but just different enough to throw you off a bit. Subway tends to localize their menus depending on the country, so it's not surprising you noticed a different selection of sandwiches and sauces in Germany.
A few differences you may continue to notice:
Cheese options: Europe often leans more toward local cheeses (like Emmental or Gouda) instead of the spicy pepper jack or American cheese common in U.S. Subways.
Sauces: They sometimes have region-specific sauces--like curry, garlic, or tzatziki-style--which can be a fun twist.
Pricing: Food service in Germany typically includes VAT (tax) and fair wages, so prices are higher than in the U.S., but tipping isn't as expected or generous.
If you're in Germany for a while, it could be fun to try one of their region-exclusive subs next time--like the Chicken Fajita, Veggie Delight with regional twists, or even rotating seasonal specials.
