Perpetual “Undefined offset” Notice in Debug.log

Hello,

Purchased and installed the PRO version of the plugin, and we’re noticing a constant notice (happens over and over again) tied to ‘Undefined offset’ and ‘Trying to get property ‘key’ of non-object’ messages:

As a result, our logs fill up perpetually (and end up unmanageably huge).

Any guidance is greatly appreciated!
