Simple Forms I18n scope "alchemy.forms" also active in "main project" and ways to prevent this

[Olli]

I use alchemyCMS as an engine. I also use in the main app simple_forms. It happens in some of my forms that the I18n lookup context is alchemy.forms .
I have no clue why this happens and why this happens in some forms and other forms work fine.
Is this a bug or some misconfiguration on my side?

Maybe it's worth to mention this in the docs
This problem can circumvented if in the main project for simple forms an scope has been explicitly set like

config.i18n_scope = 'simple_form'

Then everything works like expected.
