Hi Brayan,
If you want localize bpm texts you have to go to the IFML Project and select Project tab, go to the properties and go to the BPM tab and check Localized Model Properties.
Then you have to localize all bpm keys from localize if you don't find the key for example "Active" you have to create a new key from Custom option, you have to do right click in Custom -> Add Custom key and add key "Active " and Message "Activo"
