RoS 7.7 (stable) Missing snmp OID 1.3.6.1.4.1.14988.1.1.18

Device: CRS326-24G-2S+RM
Firmware: 7.7
RoS version: 7.7 (stable)

Checked 1.3.6.1.4.1.14988.1.1.17 - exists
Checked 1.3.6.1.4.1.14988.1.1.18 - NOT exists at all
Checked 1.3.6.1.4.1.14988.1.1.19 - exists
in terminal window there is no option under /system script print

 >/system script print  
 append  count-only  file    follow-only    from      proplist  where  brief   detail      follow  follow-strict  interval  show-ids  without-paging

I’ve checked under /system health print, option oid exists

> /system health print  oid
append  brief  count-only  detail  file  follow  follow-only  follow-strict  from  interval  oid  proplist  show-ids  where  without-paging

I need this (1.3.6.1.4.1.14988.1.1.18) OID’s to monitor IPSEC tunnel statuss.
Is it possible to fix this in future release ?
