Hi all, I am so close to finishing this process automation badge but am stuck in one area in Step 7.

I've built out my process builder as follows





And my date formula as follows
 

Case(MOD(Date__c-DATE(1900,1,7),7),0,"Sunday",1,"Monday",2,"Tuesday",3,"Wednesday",4,"Thursday",5, "Friday",6,"Saturday", "")

 

Challenge Not yet complete... here's what's wrong:  The Robot Setup Day of the Week formula does not seem to be working properly. The Day of the Week should not fall on Saturday or Sunday. 

It works nicely but doesn't seem to pass, what could be up.
 

I have followed instructions in this knowledge article for sending email templates in recipient's language: 
https://help.salesforce.com/articleView?id=000120154&language=en_US&type=1

I have the language set in the messaging:emailTemplate tag based on recipient's LanguageLocaleKey:
<messaging:emailTemplate subject="Subject" recipientType="User" relatedToType="Object__c" language="{!recipient.LanguageLocaleKey}" >
Component reference for emailTemplate, 'language' attribute: "The language used to display the email template. Valid values: Salesforce.com-supported language keys, for example, "en" or "en-US". Accepts merge fields from recipientType and relatedToType."

.. and included custom labels into the template: {!$Label.test}

There is a translation for the language I'm changing to in my settings that I'm testing for. I've also tried with apex:outputText, apex:outputLabel, etc... and still I keep getting the custom label value in English (default language).

Any ideas what I'm missing?
