As mentioned in https://wordpress.org/support/topic/bilingual-or-multilingual-wallet/#post-9741783
I have modified the plugin, so that when it is network-activated, and you edit capabilities via the “Wallets” -> “Capabilities” menu, it applies your choices across the network. I think this should be what most users would expect.
This will be out in the next patch. The next patch will be released either today or tomorrow. So watch out for the changelog of the next release.
Thank you very much for reporting this issue.

Alex
