There are no redundancy cable installed between the NPM22 modules.
The backup module can't copy configuration from primary due to the missing cable, thus its failing to go into "hot backup ready" state and a reset is issued instead.

Install a PMKHRMBRC3000A cable between them and it should fix the issue.
