Changing language of BPM notification email

Hello,

I'm working with BPM on portal 7.31.

I'm currently having a problem with the email notifcations sent by the BPM tasks: when an email is sent, the header is in the correct locale language, however, the footer is always sent in german! At least I think it's german... it says something like:

Zum direkten Zugriff auf diese Aufgabe verwenden Sie diesen Link: <http://hostname:50000//webdynpro/dispatcher/sap.com/tc~bpem~wdui~taskinstance/ATaskExecution?taskId=5d4a655a3abb11e4a926000000646c66>

Verwenden Sie diesen Link zum Aufrufen Ihres gesamten Arbeitsvorrats: <http://hostname:50000//irj/portal/?NavigationTarget=ROLES:portal_content/every_user/general/eu_role/com.sap.uwl.home_ws/com.sap.netweaver.bc.uwl.work/com.sap.netweaver.bc.uwl.uwl_page>

Does anyone know what could be happening? I already verified the locale and timezones configured for the users are correct (es and America/Colombia) and did the same for the locale and timezone fields in the tc~bpem~base~ear service... Also, the locale of the BPM DC is also es...

I have no idea where else to look.

Hope someone can help me.

Thanks!
