Mikrotik snmp monitoring High error rate trigger keep spamming

[expouser]

Hello,
I'm running zabbix 3.4.11 on Ubuntu 16.04 server.
I want connect to our monitoring mikrotik devices over snmp.
RouterOS 6.42.1
Found this template on github to monitor mikrotik over snmp https://github.com/XaTTa6bl4/zabbix-mikrotik
Template applied ok and I'm getting all the values
But one trigger is acting crazy

Trigger name: Interface 18.VMs(): High error rate
Expression: {tdl_r_gw:net.if.in.errors[ifInErrors.17].avg(5m)}>{$IF_ERRORS_WARN:"18.VMs"}
or {tdl_r_gw:net.if.out.errors[ifOutErrors.17].avg(5m)}>{$IF_ERRORS_WARN:"18.VMs"}
State: Normal]

Problem: {[URL="http://10.1.6.255/disc_prototypes.php?form=update&itemid=28564&parent_discoveryid=28562"]Advanced Template Net Mikrotik SNMPv2:net.if.in.errors[ifInErrors.{#SNMPINDEX}][/URL].[B]avg([/B]5m[B])[/B]}>{$IF_ERRORS_WARN:"{#IFNAME}"} or {[URL="http://10.1.6.255/disc_prototypes.php?form=update&itemid=28569&parent_discoveryid=28562"]Advanced Template Net Mikrotik SNMPv2:net.if.out.errors[ifOutErrors.{#SNMPINDEX}][/URL].[B]avg([/B]5m[B])[/B]}>{$IF_ERRORS_WARN:"{#IFNAME}"}
Recovery: {[URL="http://10.1.6.255/disc_prototypes.php?form=update&itemid=28564&parent_discoveryid=28562"]Advanced Template Net Mikrotik SNMPv2:net.if.in.errors[ifInErrors.{#SNMPINDEX}][/URL].[B]avg([/B]5m[B])[/B]}<{$IF_ERRORS_WARN:"{#IFNAME}"}*0.8 and {[URL="http://10.1.6.255/disc_prototypes.php?form=update&itemid=28569&parent_discoveryid=28562"]Advanced Template Net Mikrotik SNMPv2:net.if.out.errors[ifOutErrors.{#SNMPINDEX}][/URL].[B]avg([/B]5m[B])[/B]}<{$IF_ERRORS_WARN:"{#IFNAME}"}*0.8

It keeps spamming alerts every minute and send emails.
This behavior is happening for all interfaces on a device.
I checked the netowrk interface stats no RX/TX errors at all on interface.
Found this issue on a zabbix support portal
https://support.zabbix.com/browse/ZB...riority%20DESC
template settings are the same like in zabbix bug case.
and it's not working for me.
Is any one faced with this problem before.
Please share your experience how to fix this problem.

Thank you.
