Upgrading to 2.0 with whitelisting: !TSP:MSG

[Sateetje]

I've a node in my split unit air conditioner to control my airco with Domoticz. The node communicates through a repeater.

I want to use whitelisting, so upgraded from 1.5 to 2.0. Everything seems fine, I could send messages from the gateway to the node. But... I get a !TSP:MSG message in the log file.

Two questions:

1. Is this normal, see logs below
2. Is the whitelisting working/active (including signing, when I change the serial, I'll get a signing error)?

Configuration node:
#define MY_SIGNING_SOFT
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7
#define MY_SIGNING_REQUEST_SIGNATURES
#define MY_SIGNING_NODE_WHITELISTING {{.nodeId = GATEWAY_ADDRESS,.serial = {0x4D,0x8E,0x8F,0x89,0x60,0x34,0x8F,0xCC,0x43}}}

#define MY_NODE_ID 40

#define MY_PARENT_NODE_ID 10 //Repeater 1
//#define MY_PARENT_NODE_ID 11 //Repeater 2

Configuration gateway:
#define MY_SIGNING_SOFT
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7

Used SecurityPersonalizer to set HMAC, AES and a new Serial on gateway and airco-node (HMAC and AES are the same).
