Why I have a bad reading of cpu L2 cache size in CMD?

Hi guys here's the thing

If I use wmic cpu get L2cachesize, L3cachesize , I get the a wrong size for L2 and 0 for L3 cache size, but in taskmanager I get the correct readings for my cpu.

can this be an issue?

My L2 is always smaller than my L3, AMD 3.50GHz CPU has 6 cores.
