Problem getting the Case fields to work with Mail Merge when using a Word Template

Sage CRM 2017 R3

Word template is setup with fields from both Company and Case.

From Company: «Comp_Name», «Addr_Address1», «Addr_City», «Addr_State» «Addr_PostCode»

From Case: «case_caseid» «case_createdby» (and some custom case fields that I have created)

Perform a mail merge to Word or PDF from Case using a word template and the company fields show up fine in the merger. NONE of the Case fields show up.

The Case fields show up if I use an HTML template. The case fields all show up in the template editor and I am able to perform a merge to Word or PDF etc...

I am also able to have the case fields show up in an email from a work flow.

I don't want to use the HTML template as the formatting is horrible compared to a word doc.

Does anyone have any suggestions on how to get this to work?

Thanks,

John
