Shortcuts - Create email with text and attachment

Hello,

I need a help with a certain "bug" in Shortcuts app.

Most of the time I send like several types of email with pdf attachment- order conf., inquiry and invoice.

I created a template for each email, it creates new email with text and attaches a pdf, but the text is greyed out without proper format.

My guess is it is a bug in the app and needs to be resolved by Apple but I want to ask here firstly, somebody might have an idea how to fix it.

Screenshot in attachment, dont be scared its in czech lang.
