Service portal - Case - disable Rich Text Field in Additional Comment

[pgmaxmail mail]

I'm beginner to this platform 

I have created catalog form using record producer to create a case, but the issue is the activity tab, Additional comment field visible as rich text editor, so the comment will be populated as different code tags.

<p> test1 </p>

<h1>test2 </h1>

I want to eliminate those tags and add to the case comment

I have untick the instance option - Enable Rich Text Editor , but no luck

But this is working fine in customer portal because it doesn't contain rich test edition, it just a text field.

Is this a custom field? OOTB comments/worknotes are journal input kind of fields and they are rendered as plain text. Can you check the type of your Additional Comment field?
