Confirmed and reproduced (reported as MT#58402), thanks for
reporting, Jon.

The problem no longer exists in NGCP releases >=mr10.4, we'll
provide backports/hotfixes for older support releases.

FTR, with the fixed ngcpcfg behavior it will warn you about it,
like:

  base filename:/etc/ngcp-config/templates/etc/kamailio/lb/manwecustom.cfg.tt2 for:/etc/ngcp-config/templates/etc/kamailio/lb/manwecustom.cfg.customtt.tt2 not found

And if you need file permissions other than the default
(0444/-r--r--r--), you need to provide the according base filename
with the expected permissions for sure.
