Ken (K6MR) answered my question, it is a feature. I still can not find this in the K3s’s Owners Manual but Ken was 100% right.
Here is what he had to say "It’s a feature. It allows recording of the transmitted audio regardless of the monitor level. If you open Config -> Lin Out and tap 2, you’ll see t=xxx. This is the level of the output. Setting to zero should solve your problem.
