Not working on available_locales has no 'en' configuration

[ash-r1]

I'm using this gem with a non-English product.
I realized this gem crashes without :en on I18n.available_locales like that:

I18n.available_locales = [:ja] # or something excepts :en

It crashes here:

rails_admin_history_rollback/app/views/rails_admin/main/history.html.haml

Line 41 in c39e336

%td= l(object.created_at, format: :long, default: l(object.created_at, format: :long, locale: :en))

error message is:

Showing /home/ash/.anyenv/envs/rbenv/versions/3.0.3/lib/ruby/gems/3.0.0/gems/rails_admin_history_rollback-1.0.3/app/views/rails_admin/main/history.html.haml where line #41 raised:

:en is not a valid locale

Its also happening on english, checking a bit deeper looks like the new version contain a view for history witch is the one rendered instead of the version on the history_rollback gem.

Have you found what was the issue?
I'm facing the same problem on a new rails project
