Articles E-Mail Subject override doesn't work 6.0.2

Hello everyone,

we have upgraded our Request Tracker from version 4.4.7 to 6.0.2.

In the past, we used Articles as templates for communication with customers.

We also used a custom field (CF) to change the email subject.
In RT 6.0.2, this CF no longer overrides the subject.

The configuration was a single CF of type “Fill in one wikitext area”, applied to the class **“**Change email subject”.

Previously, the subject was overridden simply by applying the Article when replying, even without sending the reply.

Now, in RT 6.0.2, the subject is no longer overridden.

Does anyone know how we can fix this issue?

Best wishes
