Activitypub Custom template seems not to work

Hello, I have an issue with ActivityPub plugin version 3.0 -latest build-.

From its settings, I have set up “note” as format and from “activity” settings, I mean the template, I selected “custom” and did as follow:

[ap_title]
[ap_excerpt length="400"]
[ap_shortlink type="html"]

But going to @network@plusbrothers.net (the blog’s profile) from a Mastodon/fediverse instance, I see it with “its “customized” template’s default settings, such as:

<h2>[ap_title]</h2>[ap_content][ap_hashtags][ap_shortlink]

is it depending on the line breaks in the textarea? Should be those shortcodes attached one another? Such as [ap_title][ap_excerpt length=”400″][ap_shortlink type=”html”]?

Thanks.
