Steps to reproduce:

1. Create some service, assign tags and values like dummy1:123 and dummy2:456
2. Create service action with some media type usage, set macroses {SERVICE.TAGS.dummy1} and {SERVICE.TAGS.dummy2} usage into the message
3.  Emulate the problem situation, wait for the message - all correct
4.  Change the service tags values to dummy1:321 and dummy2:654, manually update the configuration cache with 

zabbix_server -R config_cache_reload

      5. Resolve/update the problem, wait for the message

Result:
Message contains the same service tag values dummy1:123 and dummy2:456
Expected:
Service Tag values should be changed for the macro values when problem had been resolved/updated
