InDesign 2019 automatically adds number to filename...?

[J van E]

I am using the Dutch version of InDesign and it automatically adds this to the filename when working with the files:

GEREED-C02LRR7VFH00

Anyone knows what this is...? And how to prevent it from happening? Working on an updated Mac.

Can you show us a screeenshot of this?

That's quite strange. So, before you package it's not there?

Are you using any third party plugins? Packaging from a content management system?

It happens when I save (cmd-s) an existing document. It's always the exact same code. No extensions in use. I get the idea this isn't a known InDesign option... Maybe it's system related.
