Problem when copying template with 2+ discs

[David Herselman]

We have a template which has two discs:



When we clone this template the destination disc names are inconsistent. They are however attached in the correct order and everything works as expected, the problem as such is purely cosmetic but has lead to confusion in the past:


PS: This doesn't always happen but I just cloned a template 4 times and each one had this quirk.

Herewith the content of the template:
