Zabbix LLD discovery for Cisco- issue with indexs

[batchen_regev]

Im using zabbix 4 and making my own snmpv3 template.
I have an issue that i dont undestand with LLD discovery.

For example :
I have this Discovery role :

name:Power supply status
type: snmpv3
key: cefcFRUPowerAdminStatus
snmp OID: discovery[{#CEFCFRUPOWERADMINSTATUS},.1.3.6.1.4.1.9.9.117.1. 1.2.1.1]

Discovery item :
name: Power supply {#SNMPINDEX} status
type: snmpv3
key: cefcFRUPowerAdminStatus[{#CEFCFRUPOWERADMINSTATUS}]
snmp OID: .1.3.6.1.4.1.9.9.117.1.1.2.1.1.{#SNMPINDEX}

From discovery i get only 1 shows like this in latest data :

Power supply 2014 status

2019-12-18 18:05:32

on (1)

result, in snmpwalk i get 6 results :

snmpwalk -v3 -l authPriv -u zabbix-a SHA -A PASS -x AES -X PASS 10.0.0.2 cefcFRUPowerAdminStatus

CISCO-ENTITY-FRU-CONTROL-MIB::cefcFRUPowerAdminStatus.1013 = INTEGER: on(1)
CISCO-ENTITY-FRU-CONTROL-MIB::cefcFRUPowerAdminStatus.1014 = INTEGER: on(1)
CISCO-ENTITY-FRU-CONTROL-MIB::cefcFRUPowerAdminStatus.2013 = INTEGER: on(1)
CISCO-ENTITY-FRU-CONTROL-MIB::cefcFRUPowerAdminStatus.2014 = INTEGER: on(1)

And in the Monitoring - Host - Discovery i see errors like :
Cannot create item: item with the same key "cefcFRUPowerAdminStatus[1]" already exists.
Cannot create item: item with the same key "cefcFRUPowerAdminStatus[1]" already exists.
Cannot create item: item with the same key "cefcFRUPowerAdminStatus[1]" already exists.

Its like it cannot create it, why is it trying to create always [1] ? if my index is 2013 2014 1014 1013 ? its like its taking the results ? which is on(1) ?
I think i miss understood how to do LLD discovery and zabbix only exsample is with ifDescr which doesnt help here.

Thanks

Ok i solved it, it was because the same host has the same item multipul times so i had to change :
discovery item key: cefcFRUPowerAdminStatus[{#CEFCFRUPOWERADMINSTATUS}]
To:
cefcFRUPowerAdminStatus[{#CEFCFRUPOWERADMINSTATUS},.{#SNMPINDEX}]

so it can create the same item key, it just adds the snmpindex in the end which makes it "different" item key.
