Do you have MultiCloud enabled in your environment? If you do I know for a fact there is a bug with that - one of the numbers accounts for each “record” that is relevant (i.e. that includes both Proxy and Native) where the other displays on the total correlated machines (it essentially count Proxy and Native as one which it really should). I’ve passed the same screenshot to HCL but never really bothered to open a case and deal with Support to get it documented.
