"Tiedot" is a Finnish word that means "Information", it is used inside Dynamics CRM as the default name for the two standard forms (Main and Mobile) when a new entity is created.
This is pretty obvious if the base language for the organization is Finnish, but some days ago I discovered a bug regarding the default form names, the base language for the organization was English, the Finnish language pack was NOT installed, but form name and description were in Finnish.
After a while I found that this bug is caused by the Current Format selected under System Settings, if for example you choose a different language (without installing the language pack)
You will end up with a localized form name and description: (信息 for Simplified Chinese)
My suggestion is to keep inside the development environment the same Current Format as the base language, especially when the customer will use multiple languages.
I created also a Connect feedback: https://connect.microsoft.com/dynamicssuggestions/feedback/details/902012/bug-form-name-and-description-depending-on-current-format-and-not-on-base-language
