What's the difference between the AutoXleeve silver and gold packages?

What’s the difference between the AutoXleeve silver and gold packages? Looks like Gold just has 2 more sleeves and a leg strap (which makes sense since its its $30 more), but the Silver says “VacX 3 Caps” and Gold only says “VacX 3 Cap”. Typo? Or does the Silver come with an extra VacX 3 Cap?

Silver:
4 Sleeves
Stealth Cap
*VacX 3 Caps*
Anti-Fluid Tape
Universal Harness
9 and 14oz Weighted Caps

Gold:
6 Sleeves
Stealth Cap
*VacX 3 Cap*
AntiFluid Tape
Leg Strap and Universal Harness
9 and 14oz weighted caps
