Mailcards linked to personal identities do not show the values of the variables

If you use the variables within the mailcard associated with a personal identity, they are not replaced with the values present in the personal information fields.

Steps to reproduce:

• create a new personal identity
• add an associated mailcard
• insert at least one variable that has a compiled value in the personal information
• save and reload the profile
• create a new email by selecting the additional identity created

Expected behaviour:

• the values substituted for the variables are shown in the mail card

Actual behaviour:

• the names of the variables remain in the mailcard (see attached image)
