The special price attributes provided by Commerce Exra Price Formatters are not translatable. Especially RRP. I cannot change the translations of these fields. I can write the label in the display dialog but it is not changeable depending on the site's language. How can I solve this problem?
For bugs like this, it's best to do a quick search of the module's issue queue. There are two issues, one with a patch that appears to do the job!
