To campaign editors, please think of internationalization on the most relevant languages in each case. For doing this, the configuration is:

* Id field label text: (default text)
* Page name with text for the id field label. $1 is replaced with the language code: MediaWiki:Mwe-upwiz-campaigns-wlm-xx-id/$1

where wlm-xx is the name of the campaign. Then you can create the translations on MediaWiki subpages, for example MediaWiki:Mwe-upwiz-campaigns-wlm-ad-id/es for Spanish label in wlm-ad campaign.

So, please, add for wlm-fr (I can not see any log to know who has created each campaign):
* Page name with text for the id field label. $1 is replaced with the language code: MediaWiki:Mwe-upwiz-campaigns-wlm-fr-id/$1
* MediaWiki:Mwe-upwiz-campaigns-wlm-fr-id/ca = Codi de la base Mérimée
and any other language you may consider.
