Select fields showing option-value instead option-label in e-mails

Your software
My Mautic version is: 4.4.5
My PHP version is: 8.0.27
My Database type and version is: 10.6.12-MariaDB-0ubuntu0.22.04.1

Your problem
I have created a user-defined field “salutation” of type “Selection” for contacts. Values and labels are different. If I want to insert this field as a variable in an email, I always get the value as output. However, I would like the label to be displayed.

The field is displayed correctly in the detailed view for contacts in the backend. See screenshot.

Steps I have tried to fix the problem:
I have tested the following variants.

With the variant {contactfield=salutation} I get the value displayed.
With the variant {contactfield=salutation:label} nothing is displayed.
