It doesn't look eroded. It looks like the centre electrode tip has fallen off. That shouldn't happen. I usually only use Bosch or NGK plugs. I've never heard of Auto lite...

I only use NGK or Nippon Denso plugs, for a reason after a career as a technician.
Pros: reliable, technician recommended
Denso iridium spark plugs
Pros: improved engine performance
Vehicle:
Toyota
Word to the wise, avoid using anything but the OEM recommended Champion Iridium plugs. Jeeps are pretty finicky when it comes to the sparkies.
Cons: Jeeps are pretty finicky
Vehicle:

New Denso Platinum spark plugs. Car drives great, no codes, no sputtering or stalling or hesitation.
Pros: car drives great, no sputtering
Vehicle:
Toyota MR2
NGK are my goto plugs but I’m pretty sure you’ve got the plugs that are notorious for breaking apart when removing them
Pros: goto plugs
Cons: breaking apart
Changed valve cover/gasket and installed new Bosch plugs and NGK boots.
Car had slightly higher rpms at cold startup but didn\u2019t think anything was wrong. After a few days engine started to misfire. I did some research and it sounded like I should use OEM plugs. I purchased Nissan plugs from the dealer and replaced the Bosch plugs. Misfire went away, but higher rpms at cold start persisted.
Pros: misfire went away
Cons: higher rpms at cold start
Vehicle:
Nissan Altima
Mileage: 90000 km
A few years back I bought a box set of eight Champion spark plugs that were made in Russia, and four spark plugs did that.
I've seen it multiple times in Champion in a small engine shop.
I’ve had several Denso plugs do this on a couple Camrys I service, and our own. All 2.4 cars. Caused tow ins for both husband and wife’s cars. I’ve fired denso as a spark plug provider, too many failures.
Pros: null
Cons: too many failures
Vehicle:
Toyota Camry
