Hi,
Don't know if someone have had a similar experience while editing dropdown lists with the Studio, but here's something that could be a bug.

Recently I had to customize a SugarPro 4.5.1e installation in order to add, remove and change the display value of some options for the account_type_dom in the account module.

This installation would be used in English and Spanish, so the list should be edited acordingly.

No problem with that except for the fact that when I was editing the list in Spanish the default language ( for the whole application ) was English, so after editing the values the list showed merged values from English and Spanish in the Accounts module .

After spending a few hours trying to figure what was the cause for this behavior, found the solution by changing the default language to Spanish while editing spanish values and to English while changing English values.

As I´ve said, don't know if this is supposed to work like this but the info could be useful for someone else.

Greetings,
Mauricio
