Sync Signatures from server

Hello Forum,

i’ve decided to manage all Singnatures via For Webapp/Deskapp this is working really greate - but i’ve encountered 2 strange behaviours when syncing them to Outlook 2016:

i’m using {%phone_fax} and {%initials} - in Webapp this is filled from LDAP and Initials are i.A. (short german form: im Auftrag - on behalf)
in Outlook, the template shows {%phone_fax} and the signature itself doesn’t show the number, just blank.
and the Initials are not the initials from LDAP (i.A. ) but the user fullname initials.

KOE log shows nothing special:

2018/08/10 15:25:30.680 (54,): Debug: Signatures: Updating signatures: <users_email>
2018/08/10 15:25:30.680 (54,): Debug: Signatures: Fetching signatures for account <users_email>

###manual edit
<htmlcoded signature>  -  correct with {%phone_fax} and {%initials} -  The template is successfully added
### manual edit

(mailsrv.domain, <users_email> and <username> are manual masked)

//EDIT: {%address} shows not the street address but the zipcode, city and state
any ideas why this happens?

best regards

following question:

which way is z-push (or koe) using to create the actual signature from template?
i cant see any following actions in log after copying the template but in the signature-folder from outlook there are the templates and the html-file used by outlook…

i want to troubleshoot this behaviour but i dont know how/where to start since i dont know how z-push does it.
