Check tagging location

Good day

I have been updating the tagging information for a new configuration but i am running into an issue where the tagging method i set up and the tags produced in the models are ending up different 

I am using the correct workset workspace when modeling and below is my Tag number which is used for the Pipeline name

this.PRIMARY_EQUIPMENT_NUMBER & "-" & this.NOMINAL_DIAMETER & "-" & this.SPECIFICATION & "-" &  this.SERVICE_NAME & "-" & this.NUMBER & IFF(this.INSULATION_THICKNESS = "0mm", "", "-" & this.INSULATION)

Below is what is appearing in the models

ND-SERVICE-NUMBER-SPEC-INSULATION

I suspect that it is mapping to another configuration for tagging but i am unsure how to determine this or what i need to change to fix this.

Any Help would be good

Regards
